Internet Paper Essay, Research Paper

Many people do not understand what the Internet is the power of the world. The Internet is a n extraordinary learning and entertainment tool that, when used properly, can significantly enhance a user s ability to gather information. Advanced Research Projects Agency Network (ARPANET) started the Internet. It was a project under taken by the Department of Defense (DOD) in 1969. It started as an experiment to link together DOD and military research including Universities doing military funded research. The reliable networking part involved dynamic recruiting. If one of the computers was under enemy attack, the information could be automatically transferred to other links. Fortunately, the Net is not usually under enemy attack. The ARPANET was very successful, and every university in the country wanted to sign up. Because so many people wanted to use the Net, ARPANET started getting hard to manage, especially with so many university sites on it. Therefore, it was broken into two parts: MILNET, which had all the military sites, and ARPANET, which had all the nonmilitary sites. The two networks remained connected, however, thanks to a technical scheme called IP (Internet Protocol), which enabled traffic to be routed from one net to another as needed. All the networks connected by IP in the Internet speak IP, so they can exchange messages. Even though there were only two networks at that time, IP was made to allow thousands of net works. The IP designed so that every computer on the IP network is compatible. That means any machine can communicate with any other machine. The Internet, also called the Net , is a the world s largest computer network. The Internet is the network of all networks. The networks are connected to big companies like AT&T, as well as to home computers. About 1,000 networks join each month. Every computer that is attached to the Internet is called a host. Hosts can be super computers with thousands of users, regular PC s with only a couple of user s, or specialized computers, like routers that connect to networks together or to terminal servers that let terminals dial in and connect to other hosts. The part at the right of an Internet name is called a zone. In this example the part at the right is com. Com means it is a commercial site , rather than educational, military, or some other kind of zone. The next part of the name is IECC. IECC is the name of the company. The part to the left of the company name is the name of the host machine inside the company. So a computer inside of IBM could be milton: Milton.iecc.com. Name zones are divided into two categories: the three-letter kind, and the four-letter kind. The three letter zones are made by organizations. Below is table stating all the zones:Zone MeaningCom – Commercial OrganizationsEdu – Educational institutionsGov – Government bodies and departments

Int – International organizationsMil – Military sitesNet Networking organizationsOrg Anything else that doesn t fit into any of the other categoriesThere are also two letter zones. These zones are for national countries. Some of these zones are AU for Australia and AT for Austria. There are few other zones. Even though the ARPANET is not in use any more, a few are still there for historical reasons. They have names ending in arpa. Names for some computers o the UUCP and BITNET networks, have names ending in UUCP and BITNET. These names are not real zones, but a lot of systems still route mail to them anyway. Any BITNET or UUCP site can get itself a real host name. Some parts of the Internet have rules of conduct. The strictest rules are for the NSFNET, which does not allow any commercial use. In late 1993, most educational places in the US were attached directly to the NSFNET, but then they moved to commercial networks. What the Internet does, is it transmits data from one computer to another. Each time a host wants to send a message to another host, either the receiver is on a network where the first host is directly connected (then the message will be sent directly). Otherwise the sender would send the messages to a host that can forward it. The forwarding host delivers the message directly or they can pass it to another host. Usually messages are sent to more than a dozen forwarders on its way from one part of the Net to another. One of the many great aspects of the internet is that each user has the option of remaining anonymous. Doing so would diminish the amount of prejudiced remarks said to one another. Therefore there could be no prejudices against a person who is using the internet. The Intrnet is a way for many different religions, societies, and races to meld together and share views, experiences, and new inventions across thousand of miles. Once you enter the Cyber-World, everybody is equal, deserves the same respect, and the same rules apply to all users. In my opinion the Internet is very resourceful. You can be entertained or it can be used as a teaching aid. I use the Internet all the time to either talk to people, transfer files, or look up information for school reports or projects. There are many different ways that you can log onto the Internet The most commonly used is through ISP. Some of which are AT&T WorldNet, Spectra.Net, and IBMNet. You can also access the internet through on-line programs such as America Online, Prodigy, or CompuServe. These three programs are the most popular and widely used. The Internet can be used by anyone who has a computer, modem, and Internet Program. The Internet is a necessary tool for any student who needs to do papers and reports that need the information that Internet can provide. Many schools have the Internet in class to learn form and have fun at the same time.
