History of The Internet The Internet is a worldwide connection of thousands of computer networks. All of them speak the same language, TCP/IP, the standard protocol. The Internet allows people with access to these networks to share information and knowledge. Resources available on the Internet are chat groups, e-mail, newsgroups, file transfers, and the World Wide Web. The Internet has no centralized authority and it is uncensored. The Internet belongs to everyone and to no one.
The Internet is structured in a hierarchy. At the top, each country has at least one public backbone network. Backbone networks are made of high speed lines that connect to other backbones. There are thousands of service providers and networks that connect home or college users to the backbone networks.
Today, there are more than fifty-thousand networks in more than one-hundred countries worldwide. However, it all started with one network. In the early 1960’s the Cold War was escalating and the United States Government was faced with a problem. How could the country communicate after a nuclear war? The Pentagon ” s Advanced Research Projects Agency, ARPA, had a solution.
They would create anon-centralized network that linked from city to city, and base to base. The network was designed to function when parts of it were destroyed. The network could not have a center because it would be a primary target for enemies. In 1969, ARPANET was created, named after its original Pentagon sponsor. There were four supercomputer stations, called nodes, on this high speed network. ARPANET grew during the 1970’s as more and more supercomputer stations were added.
The Essay on Arpanet Network Internet Research
The USSR launches Sputnik, the first artificial earth satellite. In the late 1960's the U. S. military was desperately afraid of a nuclear attack from the Soviet Union. The United States formed the Advanced Research Projects Agency (ARPA) within the Department of Defense to establish a bombproof network to connect military bases. ARPANET's physical network was established in 1969 to enable ...
The users of ARPANET had changed the high speed network to an electronic post office. Scientists and researchers used ARPANET to collaborate on projects and to trade notes. Eventually, people used ARPANET for leisure activities such as chatting. Soon after, the mailing list was developed. Mailing lists were discussion groups of people who would send their messages via e-mail to a group address, and also receive messages. This could be done twenty-four hours a day.
Interestingly, the first group’s topic was called Science Fiction Lovers. As ARPANET became larger, a more sophisticated and standard protocol was needed. The protocol would have to link users from other small networks to ARPANET, the main network. The standard protocol invented in 1977 was called TCP/IP. Because of TCP/IP, connecting to ARPANET by any other network was made possible. In 1983, the military portion of ARPANET broke off and formed MILNE T.
The same year, TCP/IP was made a standard and it was being used by everyone. It linked all parts of the branching complex networks, which soon came to be called the Internet. In 1985, the National Science Foundation (NSF) began a program to establish Internet access centered on its six powerful supercomputer stations across the United States. They created a backbone called NSFNET to connect college campuses via regional networks to its supercomputer centers.
ARPANET officially expired in 1989. Most of the networks we regained by NSFNET. The others became parts of smaller networks. The Defense Communications Agency shut down ARPANET because its functions had been taken over by NSFNET. Amazingly, when ARPANET was turned off in June of 1990, no one except the network staff noticed. In the early 1990’s the Internet experienced explosive growth.
The Term Paper on Internet Web Page
... within a Web Page. And these links are known as Hyper Links. The tool used to view these Web Pages on Internet is known as Internet browser or ... encourages other networks to get connected to ARPANET. Slowly the ARPANET became a massive network of networks and now it is known as 'Internet'. Internet is termed ...
It was estimated that the number of computers connected to the Internet was doubling every year. It was also estimated that at this rapid rate of growth, everyone would have an e-mail address by the year 2020. The main cause of this growth was the creation of the World Wide Web. The World Wide Web was created at CERN, a physics laboratory in Geneva, Switzerland. The Web’s development was based on the transmission of web pages over the Internet, called HyperText Transmission Protocol or HTTP. It is an interactive system for the dissemination and retrieval of information through web pages.
The pages may consist of text, pictures, sound, music, voice, animations, and video. Web pages can link to other webpages by hypertext links. When there is hypertext on a page, the user can simply click on the link and be taken to the new page. Previously, the Internet was black and white, text, and files. The web added color. Webpages can provide entertainment, information, or commercial advertisement.
The World Wide Web is the fastest growing Internet resource. In conclusion, the Internet has dramatically changed from its original purpose. It was formed by the United States government for exclusive use of government officials and the military to communicate after a nuclear war. Today, the Internet is used globally for a variety of purposes. People can send their friends an electronic ‘hello.’ They can download a recipe for a new type of lasagna. They can argue about politics on-line, and even shop and bank electronically in their homes.
The number of people signing on-line is still increasing and the end it not insight. As we approach the 21 st century, we are experiencing a great transformation due to the Internet and the World Wide Web. We are breaking through the restrictions of the printed page and the boundaries of nations and cultures.
