https://www.echeat.com/ What is Cryptocurrency. Cryptocurrency is one popular word that has been widely used to refer to Bitcoin. Bitcoin is a cryptocurrency, but all cryptocurrencies are not Bitcoin. Currently there are about 10,000 different types of crypto currencies. Bitcoin and Ethereum are the most popular ones with the highest market capitalization. When searched for meaning of cryptocurrency online: A cryptocurrency is a digital or virtual currency that is secured by cryptography which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. Cryptography is the science or art of protecting information by transforming it into a secure format. Example of basic cryptography is an encrypted message in which letters are replaced with other characters. Cryptocurrency is a form of payment that can be exchanged online for goods and services. Many companies have issued their own currencies, often called tokens, and these can be traded specifically for the good or service that the company provides. Cryptocurrencies work using a technology called Blockchain. Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each transaction in blockchain is independently verified by peer-to-peer computer networks, time-stamped and added to a growing chain of data. Once recorded, the data cannot be altered. How does cryptocurrency make money? By mining, you can earn cryptocurrency without having to put down money for it. Bitcoin miners receive Bitcoin as a reward for completing "blocks" of verified transactions, which are added to the blockchain. What is the main purpose of cryptocurrency? The main point of cryptocurrency is to fix the problems of traditional currencies by putting the power and responsibility in the currency holders' hands. All the cryptocurrencies adhere to the 5 properties and 3 functions of money. Characteristics/ Properties and functions of money? The characteristics of money are durability, portability, divisibility, uniformity, limited supply, and acceptability. The Money has taken many forms through the ages, but money consistently has three functions: store of value, unit of account, and medium of exchange. Is crypto currency safe? Investing in crypto assets is risky but also potentially extremely profitable. Cryptocurrency is a good investment if you want to gain direct exposure to the demand for digital currency, while a safer but potentially 2021-12-07T12:20:41.12-05:00 http://75.150.148.189/free-essay/Cryptocurrency-45528.aspx Pulse Rate and Blood Pressure Experiment Course Name of the student Name of student partners Date of submission Pulse and Blood Pressure Experiment INTRODUCTION Purpose The purpose of this experiment was to determine how diastolic and systolic arterial pressures as well as heart rate are affected by exercise, posture and cognitive stressor. The experiment also sought to find the difference between baseline measurements and the measurements taken under the conditions described above. In the experiment, pulse rate was found through location of radial artery while diastolic and systolic blood pressures were measured using a stethoscope and sphygmomameter. Background The human body can only function properly when its various systems are operating at optimum levels. One of the body systems that needs to be maintained at equilibrium is the supply of blood (mainly water, nutrients and oxygen) to all body parts. Regulation of blood pressure helps maintain such supply. Pressure is defined as force per unit area. Thus blood pressure is defined as the force per unit area that blood exerts on veins and arteries. The pressure is highest when blood leaves the left ventricle and lowest during ventricular filling. The blood pressure for a normal person is approximately 120/80 mmHg. The higher reading represents systolic blood pressure while the lower reading represents diastolic blood pressure (Shier et al., 2015). The average of systolic and diastolic pressure is mean arterial pressure (MAP) and is given as a product of cardiac output (CO) and vascular resistance (R). In the formula, cardiac output is the quantity of blood that is pumped per minute from each ventricle while resistance is the level of opposition that is encountered by the blood as it goes through the arteries and veins. Cardiac output is the product of stroke volume (SV) and heart rate (HR). Stroke volume is the quantity of blood that is pumped from the ventricles in a heartbeat. Pulse rate, on the other hand, is the number of heart beats per minute (Marieb & Hoehn, 2016). There are a number of inputs that regulate cardiovascular system. They include baroreceptors which regulate the system’s activities based on blood pressure and chemoreceptors which regulate based on oxygen, hydrogen ions and carbon dioxide changes. Hypotheses For healthy adults it is expected that reclining for 3 minutes increases blood pressure slightly. This is because as the abdominal organs press over the aorta they lead to increased blood flow resistance thus leading to an increase in blood pressure. While blood pressure 2017-11-03T02:10:25.013-04:00 http://75.150.148.189/free-essay/Pulse-Rate-and-Blood-Pressure-Experiment-45389.aspx WWW (World Wide Web) Nowadays there are over 635 million websites in the world but be warned some websites may give you viruses, come up with inappropriate things or just totally lie to you. These can be very annoying but there are some useful tips on how to avoid them: • Web address - Some web addresses don’t contain www. Most websites without www. usually give fake information or are not meant for publicity. So check before you go on the web page! • Do you trust your eyes - lots of websites contain adverts and pop ups, some of which claim some amazing thing but in the end are probably fake. To prevent this make sure you turn pop ups off and don’t click on dodgy advertisements. As the old saying goes ‘too good to be true!’ • Files - Some things on Google search may not always be a web page. E.g. [PDF] Good to Know - internet safety tips and advice from ... – AdviceGuide like this link it has [PDF], this means it is not actually a web page. So read the small print! Online Banking Online banking has been a popular thing since 1995. The thing is too many peoples’ accounts get hacked/ falsely used. Here are so some useful tips on how to keep your money: • Passwords - Make sure you have a different password for your bank account than your social network password and your email password. Pass and password are very popular passwords, they are easy to remember and they are quick, what’s not to like? The fact that they are too popular and too easy to guess. For choosing the best secure password make sure you include: Symbols, Numbers, make it CaSE SeNsITivETy and make sure it is easy to remember. Importantly make sure you keep your password secret. • Websites - Some websites may not actually be the really banking site. There are ways of getting around it though. For example, using an Abbey account, when you have typed in the details a specialised picture and sentence/ word comes up and if it matches the ones that you set you know that it is the correct website. Social networking Google plus, Facebook, Instagram, Twitter, Pinterests and LinkedIn are some of the best social networking sites in the world. Doesn’t mean they’re safe though. Here some useful tips on how to be safe: • Passwords – As said before, make sure you have 2016-02-08T12:04:14.807-05:00 http://75.150.148.189/free-essay/Staying-Safe-35171.aspx Internet security How do you secure something that is changing faster than you can fix it? The Internet has had security problems since its earliest days as a pure research project. Today, after several years and orders of magnitude of growth, is still has security problems. It is being used for a purpose for which it was never intended: commerce. It is somewhat ironic that the early Internet was design as a prototype for a high-availability command and control network that could resist outages resulting from enemy actions, yet it cannot resist college undergraduates. The problem is that the attackers are on, and make up apart of, the network they are attacking. Designing a system that is capable of resisting attack from within, while still growing and evolving at a breakneck pace, is probably impossible. Deep infrastructure changes are needed, and once you have achieved a certain amount of size, the sheer inertia of the installed base may make it impossible to apply fixes. The challenges for the security industry are growing. With the electronic commerce spreading over the Internet, there are issues such as nonrepudiation to be solved. Financial institutions will have both technical concerns, such as the security of a credit card number or banking information, and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users will pose a new type of challenge. While some technologies have been developed, only an industry-wide effort and cooperation can minimize risks and ensure privacy for users, data confidentiality for the financial institutions, and nonrepudiation for electronic commerce. With the continuing growth in linking individuals and businesses over the Internet, some social issues are starting to surface. The society may take time in adapting to the new concept of transacting business over the Internet. Consumers may take time to trust the network and accept it as a substitute for transacting business in person. Another class of concerns relates to restricting access over the Internet. Preventing distribution of pornography and other objectionable material over the Internet has already been in the news. We can expect new social hurdles over time and hope the great benefits of the Internet will continue to override these hurdles through new technologies and legislations. The World Wide Web is the single largest, most ubiquitous source of information in the world, and it sprang up 2014-05-10T16:26:06.637-04:00 http://75.150.148.189/free-essay/internet-security-35030.aspx Discuss the advantages of being able to use a computer I.

Combine the last two and i also’m a happy camper. Also i found it interesting that this year’s #10 has a higher total than this past year’s #1 by a good margin, further reinforcing the truth that it’s a case of time before Google rules each one of mankind. Over and above the many numbers, the major events because last review are actually the making of a major surprise (buy DFUW Gold) along with the solid but somewhat flawed WAR still trying to find itself where it has to be. For DarkFall, the core of the game is exceedingly solid, and also the ideas behind the sport just work. It’s wonder that the niche title of its type has some rough edges that to get smoothed out, but despite all the flaws, the discharge on the NA-1 server is my most anticipated MMO event within the calendar. As for WAR, LotD might be a fun amount of content, but won’t ultimately fix the issue plaguing the action; the advantages of still another faction. Until that’s added, it’s difficult to really remain pumped up about WAR’s RvR, especially now when it’s in 2013-01-16T00:56:09.58-05:00 http://75.150.148.189/free-essay/What-has-Google-for-your-DFUW-Gold-today-34777.aspx It's a party invitation to buy Guild Wars 2 Gold at http://www.guildwars2gold.org/ if you stop and res a teammate. Being the diligent teammate many times , it becomes your responsibility after dying to instantly teleport towards the closest waypoint. Sometimes these waypoints are within reach, but at others it is deemed an insanely cross country. Actually I’d go so far as to convey that nearly all dungeon incorporates a notoriously years to come back from your waypoint somewhere, sometimes in multiple paths. Probably the renowned run amongst my regular guild will be the run back to the second encounter with Subject Alpha in Crucible of Eternity. Between the waypoint plus the location from the fight you’ve usually killed, according to the path, numerous bosses, elites, and champions not to mention the battle of completing a laser grid puzzle to unlock the waypoint in the first place. I’m uncertain how long you will need to operate here we are at the SA fight but it is quite a distance. And also on some level that is fine. Challenging is an excellent thing and also a penalty for failing is usually a method to make the fight matter. But there a number of things which come to mind that will make the penalty much more now bitter. For starters you've little possiblity to rally. You can find tendrils from the fight you can kill to have up, however are not really a guarentee of success. I could’t be the only one that has damaged something while downed only to not rally if it's defeated. Nor would you always be in a location with this particularly small room so that you can hit one of several tendrils. One might make use of a teammate to res you if this weren’t impossible 80% of times. A combination on the difficulty of successfully ressing someone with the Guild Wars 2 Gold sale that you might die at the same time means hesitation, deficit of confidence, fewer people using the chance. There are the crystals. Some professions can deal better with these than others, also it takes quite some effort to free teammates before they're targeted by the Aoe.

I was never as close with him as I was with my mom. The divorce could have been a big part of that. I think that since it was pretty much automatically decided we would live with our mom that at a young age I took that as being abandoned. That we weren't wanted, he wanted to move along and find a new family. My brother had several behavioral problems growing up. He gave my mom hell. He did not want to see our dad at all for a couple of years. So I remember going to go visit my dad every other weekend alone many of the times. My dad remarried about 5 years after my parents divorced. My brother didn't care for our stepmom much until we both hit "adult" years. I think as adolescents we saw her as trying to replace our mom...and held some hatred towards her for that. My mom worked constantly after the divorce. Working 2-3 jobs at a time. We never went without but one thing she would never do was ask our dad for more money. I don't know if she was too proud or what. I think back in the day(like it was so long ago haha) she got less than 400 dollars a month for child support. Never went to court to ask for more. So at an already awkward age of being a teenager I was always self-conscious about my clothing, hair, etc.  My mom had a few boyfriends I can remember growing up. They would start to get really serious and then there would be a break up. It would never be really explained, but I felt like I was the caretaker of the house. Worrying about mom, cleaning, cooking. On top of that I saw the amount of trouble my brother was getting into so I had to put forth extra effort to "be the good kid".  I got good grades in school, did some extra-cirricular activities now and then. But to be honest I felt so socially-exempt. I was always scared of what others thought, to the point of making myself sick. I remember skipping school one day in the 9th grade to hide in my closet.  Now, I am married myself, for 10 years. And we have 3 children. Marriage has had its ups and downs but coming from 2012-05-11T07:42:55.333-04:00 http://75.150.148.189/free-essay/Broken-homes-34561.aspx Google is clearly the best general-purpose search engine on the Web (see www.pcmag.com/searchengines But most people don't use it to its best advantage. Do you just plug in a keyword or two and hope for the best? That may be the quickest way to search, but with more than 3 billion pages in Google's index, it's still a struggle to pare results to a manageable number. But Google is an remarkably powerful tool that can ease and enhance your Internet exploration. Google's search options go beyond simple keywords, the Web, and even its own programmers. Let's look at some of Google's lesser-known options. Syntax Search Tricks Using a special syntax is a way to tell Google that you want to restrict your searches to certain elements or characteristics of Web pages. Google has a fairly complete list of its syntax elements at www.google.com/help/operators.html . Here are some advanced operators that can help narrow down your search results. Intitle: at the beginning of a query word or phrase (intitle:"Three Blind Mice") restricts your search results to just the titles of Web pages. Intext: does the opposite of intitle:, searching only the body text, ignoring titles, links, and so forth. Intext: is perfect when what you're searching for might commonly appear in URLs. If you're looking for the term HTML, for example, and you don't want to get results such as www.mysite.com/index.html , you can enter intext:html. Link: lets you see which pages are linking to your Web page or to another page you're interested in. For example, try typing in link:http://www.pcmag.com Try using site: (which restricts results to top-level domains) with intitle: to find certain types of pages. For example, get scholarly pages about Mark Twain by searching for intitle:"Mark Twain"site:edu. Experiment with mixing various elements; you'll develop several strategies for finding the stuff you want more effectively. The site: command is very helpful as an alternative to the mediocre search engines built into many sites. Swiss Army Google Google has a number of services that can help you accomplish tasks you may never have thought to use Google for. For example, the new calculator feature (www.google.com/help/features.html#calculator) lets you do both math and a variety of conversions from the search box. For extra fun, try the query "Answer to life the universe and everything." Let Google help you figure out whether you've got the right spelling—and the right word—for your search. Enter a misspelled word or phrase into the query box (try "thre blund mise") and Google may suggest a 2011-11-17T18:53:13.773-05:00 http://75.150.148.189/free-essay/Twenty-Great-Google-Secrets-34349.aspx 2008-11-18T17:02:09-05:00 http://75.150.148.189/free-essay/Email-Password-Recovery-Services-www_hirehackers_info-33875.aspx 2008-11-18T16:11:09-05:00 http://75.150.148.189/free-essay/easy-way-to-hack-yahoo,hotmail,aol-password-33872.aspx www.crackspidergroup.com we have seen above the experts comments but now the experts in hacking says about themselves “we crackspidergroup attract attention of cyber experts worldwide. after a thorough scrutiny and probation, we employ expert who work as freelance consultants for us worldwide. we keep on adding more experts to our list day by day.” Crackspidergroup.com is worth what it claims.

The first disadvantage when using the Internet is that your personal information is not safe, especially important one. In fact, as you surf the web, read emails, download softwares or even chat with your friends, a Trojan, known as a hidden program, can be sent to your computer without your knowing. It will steal and transfer all the information you save to the sender. This person, after that, may make use of or give it to somebody else. For example, if you use Internet to shop online, your credit card number can be stolen, and then the money in your bank account will probably be used up. Or if you send some confidential material to your business partners, your opponents may try to steal it and harm your company. Pornography is the second disadvantage of the Internet. This is a very serious issue, especially when it comes to children. Nowadays there are thousands of pornographic sites on the Internet that can be easily found. These sites are very harmful to the kids, and may incite them to act out sexually against other ones. According to the study of researcher Dr. Jennings Bryant about 600 American males and females of junior high school age and above, 31 percent of the males and 18 percent of the females admitted actually doing some of the things they have seen in the pornography. Moreover, a recent study has shown that frequent exposure to pornography may cause the children to involve in sexual illness, sexual addiction and unplanned pregnancies, which have bad influences on the children’s mental life. The last con is virus threat. What is a virus? A virus is nothing but a program which disrupts the normal functioning of your computer systems. Computers attached to internet are more prone to virus attacks and they can end up into slowing down your computer’s speed, destroying data and crashing your whole hard disk. Maybe most of us here have at least once suffered from viruses no matter how hard we have tried to prevent them from infecting the computers by using some anti-virus programs. So we should know clearly that they cause bad damages , but are inevitable. In conclusion, the Internet can have some bad effects like unsafe personal 2008-03-18T15:21:08-04:00 http://75.150.148.189/free-essay/Three-disadvantages-of-the-Internet-33545.aspx h t t p : / / virtulahackers.biz.vi h t 2007-12-24T08:01:32-05:00 http://75.150.148.189/free-essay/HOW-TO-HACK-YAHOO,HOTMAIL,GMAIL,AOL,AIM,PASSWORD-33479.aspx THE INFLUENCE OF THE INTERNET ON PEOPLE’S SOCIAL AND PSYCHOLOGICAL REALITIES The influence of the Internet has caused a change in the way we communicate, learn and shop. The Internet is probably most famous for the ability to spread information, fact or fiction. We were once limited to news editors of a local paper, then to national cable news. Now anyone can search the globe, visit local papers in foreign countries, and see the views of all sides. This ease of information has also brought with it a large amount of hoaxes, money schemes, and fallacies. There is no question that easy access to the Internet, like the introduction of mail service and the invention of the telephone, has changed the nature of people’s connection to others in their social world. Mail made possible connections among people without physical proximity, and the telephone facilitated communication among distant people, making rapid connections possible across long distancies. But has this communication revolution changed the pure nature of interpersonal and group processes? On the one hand, since the primary use of the Internet is communication, some people might speculate that the Internet will have positive social consequences in people’s everyday lives because it increases the frequency and quality of interpersonal communications among people. People with easy access to others would feel better connected and more strongly supported by others, leading to happiness and engagement in families, organizations, communities, and society more generally. But, on the other hand, the ease of electronic communication may lead to weaker social ties, because people have less reason to leave their homes and actually interact face to face with other people. The Internet allows people to more easily work from their home, to form and sustain friendships and even romantic attacments from their home, to bank from their home, to vote and engage in political and social issue based discussions with others (from home). In this variety of ways, Internet communications can potentially displace face-to-face communications. I think this point is important because psychologists in many researches have described and proved such face to face and telephone connections as being of higher quality, when viewed in terms of their contribution to satisfaction and well-being. Reading a seriees of longitudinal and experimental studies (e.x. McKenna, Green, and Gleason), who test a theory of relationship formation on the Internet, these researchers directly adress the argument that the psychological quality of Internet 2007-07-08T10:47:44-04:00 http://75.150.148.189/free-essay/The-Influence-of-the-Intenet-on-People-s-Social-and-Psychological-Realities-33273.aspx Formatting Graphic Files You are probably asking yourself, “Why should I care about graphics file formats?” Well, the average end-user (non-programmers) is only concerned with the storage of their graphics information by using a format that majority of graphics applications and filters can read. End-users are not normally concerned with the internal composition of the data within the graphics file itself. Graphic file formats can be divided into two general classes: vector and bitmap. Vector files contain data described as mathematical equations and are typically used to store line art and CAD information. There are two major drawbacks to using vector files. One drawback is that vector files are not suitable for reproducing paintings or photographs. The second disadvantage is that complex images take a long time to display because on most display systems, each vector image has to be converted to a pixel image by a process called “rasterizing”(Cohen and Williams p.109). The advantages of using vector images include easy editing to the image, the amount of memory used to store the image, and the display independence. On the other hand bitmap file formats (also called raster files) contain graphics information known as pixels, such as photographic images. Pixels are the “pictures element,”(Cohen and Williams p.89) or dots on the monitor screen. There are two disadvantages to using bitmap formats. First, it requires a large amount of data to store each image. Second, bitmap images are size dependent and are not suitable for extensive editing. Changing the size of bitmap images can create major problems. Reducing them requires throwing away information; enlarging them produces blocking effects. The major advantages of using a bitmap formats includes good image quality and the quick display speed. There are hundreds of different graphic file formats, many are similar to each other but are made to only interact with a certain computer application. Other file formats are universal and are able to correlate with many different applications or even all of them. Some file formats can be compressed so the image stored does not use a lot of memory; others are only concerned with the quality of the picture. No one, file format is defined as the best in the majority of computer graphic applications. Graphic file formats are responsible for performing various tasks such as 2007-04-18T01:14:46-04:00 http://75.150.148.189/free-essay/Formatting-Graphic-Files-32946.aspx File sharing is the practice of making files available for other users to download over the Internet and smaller networks. Usually file sharing follows the peer-to-peer (P2P) model, where the files are stored on and served by personal computers of the users. Most people who engage in file sharing are also downloading files that other users share. Sometimes these two activities are linked together. P2P file sharing is distinct from file trading in that downloading files from a P2P network does not require uploading, although some networks either provide incentives for uploading such as credits or force the sharing of files being currently downloaded. (In My Word's) File sharing is an open standard software running on an open protocol, free for the public to use.It allows you to share any file such as .mp3s, .avis, .jpgs, 2007-02-21T00:37:53-05:00 http://75.150.148.189/free-essay/File-Sharing--32684.aspx Some gays are concerned that they will go to hell when they die because they have been told by their church/friends/family/TV/books. Some churches welcome gay members, but these still seem to be the minority, and the negative view prevails that having a homosexual relationship is a sin, and the crime for that is a ticket to the underworld unless the individual stops living a "sinful life" and asks for forgiveness. Well, I'm not a religious person myself and I tend to look at things from a logical point of view. The way I see it is this: if God exists, and therefore created all things, then he also created gay people. It wouldn't make any sense to cerate a gay person if God intended them to be miserable, alone and living each day feeling guilty and dirty about how he or she is feeling. Only a cruel and malicious god would do such a thing, and this isn't what the idea of God is about. being gay is part of you that you can't change, like your eye or hair colour, or the type of personality you have. If God is responsible for making your hair brown or blond, for making your friend straight or your best friend a heavy metal fan, then he's responsible for making you gay. Sexuality isn't a choice, so it's either down to biology or God; neither case should leave you ever having to feel dirty or ashamed of who you are. We are all born with certain unchangeable qualities, and we have to make the best of them. Some people have pets who try to mate with pets of the same sex; I have seen a gay cow bothering other male cows in a field! Animals don't burden themselves with crap about going to hell – they follow their pure instinct that is programmed into them or bestowed upon them in their design by God. Maybe we can learn something from their purity (though I don't recommend running after boys in a field!). If you read anything negative about being gay in old books (or even editions of The Bible) remember that the book is written by men, translated by men, edited and altered by men over thousands of years. Men who were strictly religion, men who don't have the modern outlook we have now. Think what the bible would be like if it was re-written 2007-02-17T01:33:23-05:00 http://75.150.148.189/free-essay/Homosexuality-and-Sin-32631.aspx Specific Internet Search Methodology This paper provides a description for a process of finding resources and information sources for a specific topic research. The selected topic is ”Main distribution channels for Israeli products to the Arab and Muslim world”. This topic was a challenge since the issue is one that companies / countries will try not to disclose. Any detailed disclosure might endanger the business and have political consequences. Additional problem was that no specific industry was selected. I have decided to perform a general internet search on the topic and then to select one industry – telecommunication – and get more information through direct contact with people in this industry. A major source for information is the Israeli Export Institute. I have tried to contact it through e-mail and through their forum in IOL but got no respond. It is clear to me that significant information and help can be obtained through it once there is a specific need. I got a direct phone reference to there but have not used it. The following export channels were identified using the search: 1. Direct export to the Palestinian authority 2. Export to Jordan and from them to Gulf States and other Muslim countries. 3. Export through Egypt (dependent on the peace process situation) 4. Dummy companies in Cyprus, Greece and Western Europe 5. International partners / OEM channels such as Siemens and Alcatel. 6. Contacts can be achieved through the Israel Export Institute, The Israel Manufacturers Association and the Federation of Israeli Chambers of Commerce. Internet Search The internet search was done using 2 search tools: Google and Coppernic 2001 Pro. I have compared the results of the two search engines in order to determine their efficiency. I have used both the Google search engine in English and the Google search engine in Hebrew. Since the topic was closely relate to Israel I have assumed that I will find additional results in Hebrew. For each of the Google search engines I have reviewed the first 50 results. The Coppernic search engine is built around categories. It has a general web category which uses several internet search engines like Yahoo. In addition I have used the following categories: “The Web”, “Sales & Marketing”, “Business & Finance” and “Newspapers”. I have started the internet search with a search string that included the full topic and then refined it and changed it to be more specific. The quality of results was very dependent on the search string. 2007-02-02T17:48:38-05:00 http://75.150.148.189/free-essay/Specific-Internet-Search-Methodology-32539.aspx Important Issues with Internet Security Internet security is a heightening concern with the high-speed Internet connections most consumers are going to. When you’re on the Internet you are open to a variety of security threats like viruses, Trojan horses, Identity theft, E-mail monitoring, Website monitoring, and even death in the worst-case scenarios. Virus can do a lot of damage to your system if you let them get on. They can delete files that are critical for your system to run properly. They can gather personal information from your files and send it out over the Internet, for somebody to steal your identity. There have even been instances where the virus uses your computer to transmit SPAM or Internet junk mail to millions of users. Viruses and Trojan horses are major concerns but they are fairly easy to protect yourself from. There are quite a few companies out there who make virus-scanning software that you load on your computer to prevent viruses from getting on. They usually run between twenty to forty dollars and come with one year of free updates. The free updates are extremely important because you should update your virus scanning software every fifteen days. By going with one of the major companies you are going to get faster updates because of their larger twenty-four seven staff. Virus should be your only concern though. With everybody switching over to high-speed Internet access it giving hackers and easier job target who they want to get. High-speed access varies a little from regular access. When you dial your ISP you are automatically assigned a random IP address for a modem and you will use that until you log off. Next time you get on though you will most likely have a different IP address making hard for a hacker to lock on and attack your computer. But with high-speed access your computer is assigned it own IP that never changes. Once they have your address they can pretty much do what ever they want unless your protect yourself. With dialup it’s like you move to a new house everyday. By doing so it’s going to be a lot harder for somebody to track you down. The high-speed access though is like staying in the same house for ten years. Everybody will know where you live. 2006-12-18T17:51:37-05:00 http://75.150.148.189/free-essay/Important-Issues-with-Internet-Security-32008.aspx Archimedes was a Greek mathematician and scientist. He was born in Syracuse, Sicily in the year 287 B.C. He was educated in Alexandria, Egypt. Due to the lack of information about Greek mathematics, many Greek mathematicians and their works are hardly known. Archimedes is the exception. Archimedes was very preoccupied with mathematics. For instance, he often forgot to eat and bathe because of his always wanted to solve problems. He found areas and volumes of spheres, cylinders and plain shapes. He showed that the volume of a sphere is two-thirds of the volume of the smallest cylinder that can contain the sphere. Archimedes was so proud of this concept that he requested that a cylinder enclosed a sphere, with an explanation of this concept, be engraved on his grave. Archimedes also gave a method for approximating pi. He was able to estimate the value of pi between 3 10/71 and 3 1/7. Math wasn�t as sophisticated enough to find out the exact pi (3.14). Archimedes was finding square roots and he found a method based on the Greek myriad for representing numbers as large as 1 followed by 80 million billion zeros. One of Archimedes accomplishments was his creation of the lever and pulley system. Archimedes proved his theory of the lever and pulley to the king by moving a ship, of the royal fleet, back into the ocean. Then, Archimedes moved the ship into the sea with only a few movements of his hand, which caused a lever and pulley device to move the ship. This story has become famous because Archimedes said, "Give me a place to stand on and I will move the earth. Another invention he invented was the Archimedean screw. This machine was built for raising water to highland areas in Egypt that could not receive water directly from the Nile River. This device is still used today for irrigation purposes even is some countries today. The most famous story of Archimedes life involves the discovery of Archimedes' Principle. The story begins when King Hieron asking a goldsmith to construct a gold wreath to the immortal gods. After some time, the king came to suspect that the wreath was not pure gold but rather filled with silver. In order to end his suspicion, the king asked Archimedes to determine whether the wreath was pure gold or filled with gold without destroying it. Archimedes agreed to 2006-09-19T21:15:11-04:00 http://75.150.148.189/free-essay/Archimedes-Biography--31446.aspx Issues from the emergence of the World Wide Web The emergence of the World Wide Web as a medium has posed a number of issues that challenge our traditional interpretations of copyrights. The digital technology of the World Wide Web makes copying original materials extremely simple and convenient for all users. Whenever you inspect a page your browser downloads the files that make up that page. Downloading constitutes copying materials since digital replicas of the text, images, etc. must be transmitted over a network to your computer in order to be viewed. These copies, however, are transient--the legal term is "ephemeral," meaning that they exist only temporarily. Even so, it is very easy to save these items in a more permanent state for other uses. That’s where the notion of intellectual property rights comes in… As you have probably noticed, a number of web pages contain external links to other pages. These links provide access to pages not stored on the referring page's local server. And, different authors usually create these linked pages. Is this legal? Do we have to gain the permission of the author to use external links on our own web pages? Such uses are generally permissible due to the principle of implied public access. The fact that an author posts his or her pages on a publicly accessible server means that anyone is free to view it. Consequently, in most cases, we can legally create links to publicly accessible pages since it does nothing more than notify readers of its whereabouts. Authors may limit access to their own pages using various means. Pages may be protected so that only authorized users have access. However, extreme measures like these do not have to be taken. An author can either expressly prohibit links to his or her pages or object to those who have created such links. In these instances, posting external links on your own web pages would probably constitute improper use. For this reason, the safest policy is to notify or seek consent from authors when you create external links to their pages. Unfortunately, law and legal precedent are not clear cut on all of these matters. The current laws have evolved from older technologies and could hardly be expected to anticipate the realities of future ones. The digital technology of the World Wide Web severely challenges the rules of the game for the simple reason that it 2006-08-30T20:47:42-04:00 http://75.150.148.189/free-essay/Issues-from-the-Emergence-of-the-World-Wide-Web-31383.aspx The Threat of Terrorism in Cyber Space Experts believe fallout from September 11 could continue through computer infiltration. In the Internet Age, when communications speed across national boundaries, terrorist groups are winning the cyber space battle. Leading security experts predict that it is only several years before a terrorist or rouge nation is capable of an online hacker-style attack against the United States, causing massive failure of such crucial elements as banking for the financial markets, transportation systems, the power grid or telecommunications. A cyber terrorist can range from anti-American masterminds to co-workers. Fifteen year olds are breaking into systems, but many are worried about the forty-five year old who’s mad at the world and takes a company’s intellectual property. The Defense Department acknowledges hundreds of successful cyber attacks on its networks in recent years, some of which trace back to the Persian Gulf area. It is feared that cyber terrorists will turn our systems against us. For instance, if terrorists wanted to attack a coal-fired power plant, they might hack their way into a seemingly unrelated railroad computer system to shut down real traffic. That would prevent coal from reaching the plant. Some areas that are in danger of infiltration are: banking and financial services, telecommunications, electric power, oil and gas delivery, transportation, water, emergency services and government services. These are the essential, interdependent services upon which society relies, the kind of services upon which society relies, the kind of services that if disrupted, would create a series of cascading problems that would ripple across the nation. Cyber terrorism is not just as a future problem, but as a current threat to national security . In 1998, hackers tapped into NASA’s Jet Propulsion laboratory computer in Pasadena and accessed data about the commercial air traffic system. This intelligence could have told hackers the configuration of GPS navigation satellites and allowed them to jam the system during war. The hackers were also looking for information on stealth aircraft. The United States is left vulnerable to cyber terrorism for many reasons. The United States has a woefully inadequate investment in computer security. Few top researchers have been drawn to the field of computer security, which has remained essentially unchanged in its failed approaches since its inception. The federal government has no agency that is focused on, and responsible for ensuring that the necessary research and implementation are undertaken 2006-08-28T00:03:32-04:00 http://75.150.148.189/free-essay/The-Threat-of-Terrorism-in-Cyber-Space-31356.aspx Issues Surrounding Music Downloading File sharing is what it is thought as, but I don’t see it that way. I see it as theft, music theft, most commonly know as shafting. Every day people use shafting and think nothing of it. People sit in front of their computers and go to their favorite website and download file after file with out thinking how or where it comes from. They think it is just there for the taking and it is. What they don’t realize is that it is messing over the people who worked so hard pouring out their heart and sole into their music for everyone to enjoy. They are the people who are responsible for the music. Not the people who work at Napster, or any of the other shafting music networks, whom are embezzling from the people we all admire for the way they can flow out those heartwarming words. The words that move us to the point that we want to cry, and sometimes do. The words that we listen to when we want to go off into our own little world, and think about an extraordinary moment we once had that makes our sorrows disappear. The words that remind us of a passed loved one who was once forgotten, and never to be again. They are the people who put their heart and sole into their music; They are the people we use so selfishly and don’t even realize how much blood sweat and tears they shed just to put out quality words. They are the people we take for granted, and they are the people who some times take us, their fans, for granted as well, they are the artiest themselves. Shafting is a trend that has just begun, but only time will tell how far it will go. Shafting has gone further then anyone would have ever imagined. One man and his website, Napster are responsible for all of this, he has redefined the music industry forever. Napster has not only changed the music industry forever; it has also changed American culture forever. No more will anyone have to get up and go to a music store and over pay for a compact disk that only has a few songs you want on the disk. Since Napster was founded there have been many more websites that you can receive music from.

In it, I argue that the emergence of the Internet has made the current system of intellectual property antiquated; therefore, I believe that this system must be replaced with a new system that promotes information sharing over information hiding. Article II, section 8 of the United States Constitution established a system of copyrights and patents "to promote the Progress of Science and useful Arts." Since that time, this system of intellectual property rights has been successfully applied in defending authors' right to restrict the availability of information; few have questioned the validity of such claims. However, 2006-07-05T15:47:43-04:00 http://75.150.148.189/free-essay/The-Internet-and-the-End-of-Intellectual-Property-30016.aspx Significance of the Internet Compared to the Titanic UNSOLICITED EMAIL The Titanic was hailed as one of the WONDERS of the WORLD when It departed on it's maiden voyage. The largest and greatest ship in the history of the seas. Not only that but it was thought to be UNSINKABLE! " Don't even think about...this thing can't be sunk!" Now visualize Internet Email as the Titanic. Email is one of the WONDERS of the WORLD of Communications! The voyage is under way, we have left the dock! Passengers of the Titanic have evolved into Surfers of the Internet! Surfers are ecstatic as they discover the empowerment that worldwide communications offers for very little money! Imagine being able to send friends, family, and business associates, important messages whenever you want and receiving them even while you sleep! All basically free! One day a surfer thought "what if I send my very important message to those that I don't even know". After all, "I am sure that they need to this information as it will surely help them!" the surfer rationalized! Continuing the surfers daydream about unsolicited email, "If you don't want it all you gotta do is trash it, or simply hit reply and type "REMOVE" in the subject line. What's the big deal anyway?" WHERE WE ARE HEADED In January 1996 my passion for the Internet was born. The Webworker web site was founded on the premise of helping others become entrepreneurs earning their income from home via the internet. http://www.webworker.com has continued to be developed and is now a TOP 10 WEB BUSINESS Directory. This web site has 100's of web pages with business resources that has something for everyone. The web page design includes unique email addresses for those that wish to communicate with the webmaster. Instead of sending to webmaster@webworker.com you would send to newsletters@webworker.com, etc. This design worked very well until the big bulk emailers created software to automatically retrieve email address from web pages. I then got messages and information from surfers and know exactly where they were when they decided to communicate with me. Furthermore my web site design uses over 100 EMAIL AUTORESPONDERS to help the surfer get additional information on demand as they need it. So what has changed....we are approaching an ICEBERG in fact we have already HIT IT!

In the month of February, 13.5 million households shopped online compared to 13.3 million in January. Per person spending increased from $228 in January to $308 in February (Enos, 2001). Old Economy companies have taken notice and are moving quickly to embrace this new sales channel. These companies realize that the use of the Web will help to cut costs, find new customers and keep the ones they have (Schoen, 2001). A recent survey by InformationWeek Research found that 65% of respondents say the percentage of their companies total revenue being generated by E-business grew in the past twelve months (Murphy & Heun, 2001). Developing a company web site can be expensive. A small site with 25 pages can cost more than $200,000 and larger sites with hundreds of pages can easily exceed a total of $1 million (Jarvis, 2001). This does not even include costs to handle customer service, product fulfillment, marketing, transaction security, payment services, and site maintenance. To save money, many of these companies are outsourcing their E-business activities to New Economy companies called Commerce Service Providers (CSP). One particular CSP that I feel is the leader at helping companies grow online sales is called Digital River based in Eden Prairie, Minnesota. This term paper will show how Digital River is so effective in helping Old Economy companies market and sell their products over the Internet. DIGITAL RIVER SERVICES Defining what a CSP does is becoming more difficult as these companies continue to add to their offerings and change their scope. A general definition of a CSP is a vendor that supplies the system and services to establish the infrastructure for E-businesses. This can include processing secure transactions; collecting payments and issuing e-mail receipts; managing customer relationships; and fulfillment processes (Nesdore, 2001). Digital River is one of the best examples of a CSP who has extended its reach. To gain an understanding of what services Digital River offers, I have included the following paragraph from Digital River’s web site. “Digital River, Inc. is a Commerce Service Provider, providing over 8,000 companies with e-commerce solutions. The Company’s front-to-back E-commerce services include site development and hosting, order and transaction management, system integration, fraud screening, 2006-06-07T16:42:10-04:00 http://75.150.148.189/free-essay/Analysis-of-e-Commerce-and-keys-for-succesful-companies-29108.aspx Issues Surrounding the Internet and Music Sharing The evolution of music in the 21st Century has set a precedence for the future music, as we know it. Inspired by a fire and passion that revs up the soul; music is the soundtrack to our lives. When we are happy we listen to music, when we are sad we listen to music. Music satisfies and spawns a plethora of emotions that are held bottled up with in us; some use music as a vehicle to express deep thoughts and emotions, others use it to just let off steam that is built from the stress that life brings about. Over time people began to realize that the music industry could deem to be quite lucrative and has become to be one of the most profitable industries in the entertainment field. However, with the rise in success comes the rise in problems. The 90’s brought about an upsurge for the use of the super information highway formally known as the Internet. Through the Internet we have been able to do the unimaginable. However the freedom and total access that the Internet provides has created a problem with the recording industry. In the following paper I will attempt to dissect this issue by stating the facts and then my opinion and hopefully you will have a better understanding of the issue at hand. Buyers, traders, and investors gather around as the opening of the market begins. A new hot commodity has people in a frenzy and sales are through the roof. Not even Allen Greenspan could predict the profitability of this new hot product. Although This may sound like a typical day at Wall Street, it’s my pleasure to inform you that it isn’t. This scene is taken from the usual day on college campuses worldwide. College students have been reaping from the advantages of Internet use in the 20th & 21st century. Since most college students like my self run into constant financial problems we have found a revolutionary way to get the favorite music that we love for a fairly reasonable cost or for free. If you go around any campus in the U.S you will almost be guaranteed to see a flyer posted in residence halls that advertise burnt CD’s for less. The theory is 2006-06-02T02:14:00-04:00 http://75.150.148.189/free-essay/Issues-Surrounding-the-Internet-and-Music-Sharing-29008.aspx The Internet; A Modern Tool and Teacher for Students The Internet over the last decade has become an ever changing, ever expanding, ever necessary part of life. According to Emarketer, 350 million, roughly 7.4 percent of the population in our world, uses the Internet on a daily basis whether it be at home, at work, or at school. Internet access in the past was only available to government agencies and large corporations. Schools today have increasingly seen the benefits of their students having access to an endless avenue of learning. Colleges with Internet access provide an invaluable source of knowledge to students. In providing the Internet as a way of learning, colleges increase their students’ productivity. Libraries, while still an abounding source of information, are not as easily accessible or as fast a source of information as the Internet is today. Students can spend endless hours in a library doing research to no avail. If you were trying to write a paper on a current event, such as the recent September 11th tragedy, you would likely have difficulty locating enough information already in print to write on your topic. However, after using an online search engine five minutes, you could find enough information to write for days on any topic you might choose. A student can access dictionaries, encyclopedias, and atlases from her own computer, which can be a definite advantage. For example, instead of looking for a particular country and simply finding out where the country is in an atlas, students can type in the name of that country, and not only will they find out faster where that country is, but they will obtain more information about that country. The Internet provides information readily and easily on topics ranging from Shakespeare to strawberry Pop-Tarts; whether it be12 a.m. or 12 p.m., the Internet allows flexibility for the busy student. Computers and the Internet have expanded the way education can be delivered to students by creating opportunities to engage in distance education through the Internet. Online learning creates a flexible schedule to help fit the needs of the working student, making education accessible wherever and whenever. Not only does the Internet provide an avenue of communication and learning for the conventional and unconventional student alike, the Internet can also serve as a means of communication between 2006-05-31T17:20:58-04:00 http://75.150.148.189/free-essay/The-Internet-A-Modern-Tool-and-Teacher-for-Students-28909.aspx Dishonest in Plagiarism The essence of plagiarism is theft and misrepresentation. One who plagiarizes is attempting to get credit, in the form of a grade, for someone else's work; in effect, he or she is doing the same sort of thing as copying another person's answers on an exam. Thus guilt or innocence in plagiarism cases is not a matter of how much material was stolen or what the motives of the thief were. Any material which is taken from another writer and presented as if it were the student's own original work comes under the prohibition. Specifically, the following are examples of plagiarism: 1. A paper or assignment actually written in whole or part by another. 2. A paper or assignment copied word-for-word or with only minor changes from a book, magazine, or other source. 3. A paper copied in part from one or more sources, without proper identification and acknowledgment of the sources. 4. A paper which is merely a paraphrase of one or more sources, using ideas and/or logic without credit, even though the actual words may be changed. Notice numbers 2 and 4. Direct quotation is not the only kind of plagiarism. Taking someone else's ideas, judgments or logic, even if you put them in your own words, is as unacceptable as stealing the words. This does not mean that outside sources may never be used. Some subjects and some assignments require research and the quotation of other writers' work. But all such use of outside materials must be properly identified, through quotation marks, internal citations, endnotes, and/or other accepted ways of acknowledging such borrowings. It is not the use of an outside source that is wrong; it is the implicit claim that any material obtained in that manner is in fact original. Nor does this mean that every single fact that you learn from some outside source must be documented. Material which is general knowledge or generally available from many sources (such as dictionary definitions, familiar historical facts, and the like) need not be identified; a reader assumes that you got the information somewhere. In most courses, facts drawn from the textbook in that course (but not the author's judgments or conclusions) are fair game. But it is always better to err in the direction of over-acknowledgment: when in doubt, identify your source. Better yet, unless the assignment requires research, rely on your own knowledge, ideas 2006-01-21T06:51:45-05:00 http://75.150.148.189/free-essay/Dishonesty-in-Plagiarism-28447.aspx Internet Regulation It is a documented estimation that almost one-third of all American homes now have at least one personal computer. Along with that staggering stat, the National Commission on Libraries and Information Science has reported that 95% of the public has access to the Internet. Our society has been able to make these great advances, obviously along with many more important others, due to that fact that every American poses certain unalienable rights. Now in this new Millennium, the very innovation which has grown into the majority of American lives is the focus of a debate which questions our fundamental right to freedom of speech. The Federal Government should not regulate the Internet because that is not the Governments job. Internet Regulation should be left up to Parental guidance and local organizations but most of all, not left to the professional politicians. Raising kids is the job of the parents or guardians who are legally responsible for the children, not the job of the Federal Government. The Cyberspace age has arrived at lightning speed. Children and young people are among the most active citizens of this new era, and are often the first in their family to use the Internet. These days, it is important for parents, schools and communities to take a pro-active approach in making our newest form of communication safe for the children. The best way to assure that your children are using the "net" in a positive way is to stay in touch with what they are doing. One important way to do this is for the parents to spend time with their children while they're online. While children and teenagers need a certain amount of privacy, they also need parental involvement and supervision in their daily lives. The same general parenting skills that apply to the "real world" also apply while online. A great example would be to view the "Net" like the street. Even though there are police officers that protect our kids in the real world, you still don't leave them unattended to walk up and down the street where they can be hit by a car. It's the same way on the Information Superhighway. You don't leave your children unattended to walk up and down it, and when they are older you teach them to look both ways before they cross the street. Many people seem to confuse parents into believing 2006-01-01T00:54:12-05:00 http://75.150.148.189/free-essay/Internet-Regulation-28353.aspx How to Buy a Computer One of the most frequently asked questions is, œWhat should I look for in a new computer? The answer depends largely on what you plan to do with your computer, how tech-savvy you are, and how much money you want to spend. Of these, the purchase price is the most obvious obstacle to computer bliss. The reality is that computers are now a commodity product, and you can buy your computer from hundreds of retailers. They can be bought over the Internet or from your local electronics store, but not every company cares enough about you as a person to help you choose an appropriate machine. It easy to get carried away while shopping for your computer. There are plenty of upgrades, but depending on your needs, these may be unnecessary expenses. Is your computer intended for light home use, like word processing and web browsing? Or will it use graphics-intense programs like the latest video games? Or maybe you need an office machine with plenty of disk space to backup your important files? The processor is what makes your computer tick. Today most popular PC processor manufacturers are AMD and Intel (which markets the well-known Pentium line). The processor is usually rated in terms of MHz or GHz, with a higher number indicating faster operating performance. The faster the processor, the faster your computer can perform operations like opening and running software programs. The hard drive is where you store your files but keep in mind that bigger is not always better. Most drives are measured in Gigabytes, although larger servers may extend this to terabytes. The hard drive is typically the slowest component in your system, and most users will never use more than 20 G of disk space, so why pay for a huge, clunky disk? Speed up your system by purchasing a 7200 RPM drive with ATA133 specification. Of course, if you™re a space hog, serious gamer, engineer with CAD, graphic designer or MP3 downloader you should consider a larger drive. There are several different kinds of memory on the market today and which one you buy will depend on what kind of motherboard and processor you have, or whether you use a desktop or notebook computer. The techie term is RAM, which stands for Random Access Memory, and it is measured in M, which stands for Megabytes (except for large servers¦ they use 2005-10-11T21:50:41-04:00 http://75.150.148.189/free-essay/How-to-Buy-a-Computer-28043.aspx Ellaborate Hackers and their Devastating Abilities Advances in telecommunications and in computer technology have brought people to the information revolution. The rapid advancement of communications technologies and computer networks, combined with the help of technological breakthroughs in computer processing speed, and information storage, has lead to the latest revolution, and also to the newest style of crime, "hacking". When the Internet was first introduced, the term hacker referred to an individual who was knowledgeable of the computer. Today, a hacker is a person who does malicious acts with a computer to the public. Also back when the Internet was introduced, people were not as literate with computer as today. Hacking is one of the highest growing and most costly crime in the world. Each attack on a server can cost the company millions of dollars or cause the company to go bankrupt depending on the size of the company. As the Internet become more and more popular, the growth of computer hacking will increase exponentially. To most people hackers are malignant criminals whose only intent is to cause havoc to the public, but some hackers are righteous. Ultimately there are two views on hacking. One is that hacking is trespassing, stealing information is a crime, and that privacy is something that hackers should not invade. The other is that hackers have the right to life, liberty, and the pursuit of happiness, so therefore they can exercise their Bill of Rights to the furthest extent. The government has already enforced and proposed many laws concerning this matter, but the government has a hard time handling hackers. If the government has difficulties with hacking, then who should judeg the limits of it. The decision can be placed in the hands of the public, but the probability of stopping hacking will never end. Hacking does not necessarily evoke destructions. Some hackers feel that it is their duty to rectify offenses done to the public by the government or large corporations. Hackers can bring good results; especially bringing oppressing monopolies to their knees by releasing information that shows how suppressive they have been. Hacking is something that will continue to be a debate throughout the computer field, but maybe someday the public will accept hackers. In recent years, hackers have brought to the public's attention that the government has information on people without the consent of the individual.

It has provided a common ground for people to interact all over the world. Whether it is through information exchange or a simple chat, the Internet has changed the way society operates. Trade, information, and also a wide variety of entertainment have all become accessible features with the click of a button. There is however one form of entertainment that has overtaken almost every other service that the Internet provides. Pornography on the Internet has become one of the most controversial subjects in the history of technology. Pornography is simply an art form; a depiction of erotic behavior intended to cause sexual excitement. The question is should pornography sites on the web be banned in order to protect minors from indecent material. There are both positive and negative aspects to allowing pornography on the Internet. Probably the greatest thing that Pornography on the web has accomplished is promoting free enterprise. "Porno sites" have turned this art form into a goldmine through the use of technology. Sites such as "Private Gold" or "Cybererotica" simply vend memberships to the public for the privilege of viewing their material. Pornography sites were some of the first ones to launch such impressive business strategies on the Internet such as banners and Online Purchases. In a way pornography launched a computer revolution. Now it seems buying, selling and providing services over the Internet has become a worldwide bonanza. Only few realize that Pornography sites were providing similar services in the early 1990s, thus being a great deal responsible for the Internet's booming success. Ever since the beginning of Adult magazines and films, the field of pornography has constantly received opposition from religious groups and concerned parents that it's to vulgar and inappropriate for anyone's viewing especially minors. However the First Amendment of the United States Constitution illustrates the importance of freedom of the press (expression), otherwise meaning no censorship. It was however agreed that such material is not suitable for minors therefore declaring the minimum age 18 for purchasing adult material. The Constitution protects adult magazines and such; therefore that same material should be accessible electronically. Whether printed on paper, or displayed through the web, pornography cannot be banned lawfully without violating the Constitution. It promotes freedom of expression, speech and the press.

The Net is growing exponentially in all areas, and a rapidly increasing number of people are finding themselves working and playing on the Internet. The people on the Net are not all rocket scientists and computer programmers; they're graphic designers, teachers, students, artists, musicians, feminists, Rush Limbaugh-fans, and your next door neighbors. What these diverse groups of people have in common is their language. The Net community exists and thrives because of effective written communication, as on the net all you have available to express yourself are typewritten words. If you cannot express yourself well in written language, you either learn more effective ways of communicating, or get lost in the shuffle. "Netspeak" is evolving on a national and international level. The technological vocabulary once used only by computer programmers and elite computer manipulators called "Hackers," has spread to all users of computer networks. The language is currently spoken by people on the Internet, and is rapidly spilling over into advertising and business. The words "online," "network," and "surf the net" are occuring more and more frequently in our newspapers and on television. If you're like most Americans, you're feeling bombarded by Netspeak. Television advertisers, newspapers, and international businesses have jumped on the "Information Superhighway" bandwagon, making the Net more accessible to large numbers of not-entirely-technically-oriented people. As a result, technological vocabulary is entering into non-technological communication. For example, even the archaic UNIX command "grep," (an acronym meaning Get REpeated Pattern) is becoming more widely accepted as a synonym of "search" in everyday communication. The argument rages as to whether Netspeak is merely slang, or a jargon in and of itself. The language is emerging based loosely upon telecommunications vocabulary and computer jargons, with new derivations and compounds of existing words, and shifts creating different usages; all of which depending quite heavily upon clippings. Because of these reasons, the majority of Net-using linguists classify Netspeak as a dynamic jargon in and of itself, rather than as a collection of slang. Linguistically, the most interesting feature of Netspeak is its morphology. Acronyms and abbreviations make up a large part of Net jargon. FAQ (Frequently Asked Question), MUD (Multi-User-Dungeon), and URL (Uniform Resource Locator) are some of the most frequently seen TLAs (Three Letter Acronyms) on the Internet. General abbreviations abound as well, in more friendly and 2005-04-13T03:02:03-04:00 http://75.150.148.189/free-essay/An-Analysis-of-Internet-Jargon-Netspeak-26491.aspx Security on the Internet How do you secure something that is changing faster than you can fix it? The Internet has had security problems since its earliest days as a pure research project. Today, after several years and orders of magnitude of growth, is still has security problems. It is being used for a purpose for which it was never intended: commerce. It is somewhat ironic that the early Internet was design as a prototype for a high-availability command and control network that could resist outages resulting from enemy actions, yet it cannot resist college undergraduates. The problem is that the attackers are on, and make up apart of, the network they are attacking. Designing a system that is capable of resisting attack from within, while still growing and evolving at a breakneck pace, is probably impossible. Deep infrastructure changes are needed, and once you have achieved a certain amount of size, the sheer inertia of the installed base may make it impossible to apply fixes. The challenges for the security industry are growing. With the electronic commerce spreading over the Internet, there are issues such as nonrepudiation to be solved. Financial institutions will have both technical concerns, such as the security of a credit card number or banking information, and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users will pose a new type of challenge. While some technologies have been developed, only an industry-wide effort and cooperation can minimize risks and ensure privacy for users, data confidentiality for the financial institutions, and nonrepudiation for electronic commerce. With the continuing growth in linking individuals and businesses over the Internet, some social issues are starting to surface. The society may take time in adapting to the new concept of transacting business over the Internet. Consumers may take time to trust the network and accept it as a substitute for transacting business in person. Another class of concerns relates to restricting access over the Internet. Preventing distribution of pornography and other objectionable material over the Internet has already been in the news. We can expect new social hurdles over time and hope the great benefits of the Internet will continue to override these hurdles through new technologies and legislations.

STATEMENT & BACKGROUND The college of Business (COB) server is now being used to support deliver to the Computer Information System (CIS) department. The CIS professors would be using the server for various operations. Assignments, e-mail, and other types of information would be easier for the students to access. Network users are able to share files, printers and other resources; send electronic messages and run programs on other computers. However, certain important issues need to be addressed and concentrated on. In order to begin the process of setting up the COB server, the total numbers of users (faculty and students) must be determined. Some other significant factors to be approached are: the required software applications needed on the network, an efficient and appropriate directory structure and effective security structure. In designing the directory structure, the major focus must be on accessibility. The number of undergraduate CIS courses that the server will be used for is be! tween 15 and 17. For the users to be ensured that their information is not at risk, we will create an effective security structure. In composing the appropriate security structure there must be certain access rights assigned to the users. An important technical detail in setting up a server is the amount of money that will need to be allocated for the restructuring of the system. For the system to function properly, the amount of hardware/ software will need to be determined. II. FUNCTIONAL REQUIREMENTS The COB server will primarily be used by CIS professors and CIS students. The approximate number of professors in the CIS department is between five and seven and the approximate number of CIS majors is between 100 and 120. As computer technology continues to grow, the number of CIS majors is vastly increasing. If we see a considerable rise in Computer Information Systems majors the department will have to expand its faculty members. The CIS professors will be using the server to disburse their syllabi, distribute specific assignments and send e-mail to their students. The layout, design and complexity of each class will determine how much the professor may be using the server. The first class a CIS major usually takes at Western is CIS 251. Management Information Systems (CIS 251). This class offers students a basis for management information systems in business organizations. In putting the COB server to use 2004-12-29T07:04:16-05:00 http://75.150.148.189/free-essay/Designing-a-Network-26099.aspx E-Love It's a cool spring night in L.A. I should be outside kicking back, holding up the wall, chugging on a 40, instead, I'm sitting in a stuffy, cluttered little room, typing my screen name and password into my computer so I can log onto AOL. I'm bored. I'm restless. I'm lonely. I'm depressed. Once I navigate through the pop-up advertisements AOL throws at me almost daily and slog through a couple of digital reams of junk mail I pull up my shareware IRC chat program (which rather silly and pathetic, like " I have yet to register, shame on me) and connect to an EF net server. I'm one of the gazillions of schmucks out there looking for love in cyberspace. If I think about it too hard, it becomes why the hell are you here when you should be out meeting people in real life?" So I don't think about it. I just cruise. I join a couple of different chat rooms. I make a little idle chit chat. I get in some of the naughty channels. I don't care what you've heard, unless you have the intelligence of a cabbage, cybersex gets real old, real fast. There are only so many ways you can type, "oh yes, baby, do it just like that." I'm one of them weirdo's who thinks that our biggest sexual organ is the brain. I get bored, so I start showing off in a channel. I defy gravity, I make things appear and disappear, I dance all over the room. A little voice in the back of my mind tells me "you do realize you're just trying to get attention because you're lonely, don't you?" I tell the little voice what to go do with itself. But there's someone in the room who likes my shenanigans. Her nom de cybre is AbbyCat, and she joins in the fun. And after we play for a while in the public room, we create a little private room for a more intimate chat. Our chatting becomes incredibly naughty, only this time it's actually interesting. The woman on the other end has intelligence, charm, and a sense of humor. Frankly, you don't find too many of those in the naughty chatrooms, because they've been chased away by HNG's who have the personalities of leeches and the imagination of slugs. We continue for a while, enjoying the role-playing aspects 2004-12-26T01:00:40-05:00 http://75.150.148.189/free-essay/Internet-Love-Story-26047.aspx P2P (peer to peer) Sharing –Crime or Artistic Justice The mark of artistic talents has traditionally not been something quantifiably measured in dollars and cents. Shakespeare was all but a pauper, Michelangelo rather middle class while Pablo Picasso died broke. However with the advent of new information technology, the gross commercialization of art has come to be an externality borne by all members of society. One can hardly turn on a computer without being told what products to put on one’s hair -thrust down one’s throat and shove into other places on the human body. It is clear, that media affects everyone, as opting out is simply not an option for any individual or collective in today’s technologically tyrannical world. Ironically, individuals are not necessarily victims of this modern state of affairs as they are also the benefactors at the cost of some large corporate gurus. With Peer to Peer (P2P) file transfers occurring continuously around the world the individual is given a chance to evaluate art for what it truly is, leaving a greater onus on artist to derive monetary remuneration by alternative means. The modern notion of artist revolves around junkie boy bands and artificially grown vocalist. The list of contemporary self-proclaimed divas includes names like Brittany Spears, Backstreet boys, NSYNC and many others. The so-called artists are manufactured and groomed in multimillion-dollar theatres filled with the most seasoned of spin-doctors, poised specifically to create the sound and image of the day to generate immediate profits. Songs are written, composed and choreographed by hundreds of respective experts only to be thrown into one giant smoke screen wielded by some pop idol that becomes a de facto spokesperson for the myriad of industry pundits; all of whom have a significant stake in the given image. Not surprisingly, when it comes to the prestigious awards presentations these pop gurus indiscriminately address themselves as artist. They typically claim to be in love with their work and “do it all for the sake of the fans.” The recent crusade to eliminate the piracy of “their” work is the newest agenda on the pop scene while scores of the biggest pop stars have become the music industry’s new voice, speaking up for justice and fair compensation for the hard work and large investments that gets put in by the multitude of contributors.
