The Internet

Extracts from this document...


The Internet The word Internet stands for International Network. The Internet is a collection of thousands of computer networks throughout the world. The linked networks may be either LANs or WANs, most of them are owned by individual organisations. Some WANs such as CompuServe act as Service Providers. The Internet has had a relatively brief, but explosive history so far. It grew out of an experiment begun in the 1960s by the U.S. Department of Defence. The Department of Defence wanted to create a computer network that would continue to function in the event of a disaster, such as a nuclear war. If part of the network were damaged or destroyed the rest of the system still had to work. The Internet is a network of networks that connects computers all over the world. The Internet has its roots in the U.S. military, which funded a network in 1969, called the ARPANET, to connect the computers at some colleges and universities where military research took place. ...read more.


The World Wide Web is what draws most people onto the 'Net'. A web address contains three w's at the beginning of it. The www allows users to the 'Net' to publish multimedia pages, containing text, graphics, sound and video information. Each website on the Internet has a unique address, starting with the letters http:// (Hyper-Text Transfer Protocol). These Web addresses are known as URLs (Uniform Resource Locators). Computers connected to the Internet communicate by using the Internet Protocol (IP), which slices information into packets (chunks of data to be transmitted separately) and routes them to their destination. Because the Internet was designed to operate during wars, it uses dynamic routing, so that if even one part of the network is knocked out, packets can be re-routed around the problem. The hardware and software required to use the Internet are as follows: * A computer * An ISDN connection or a modem and telephone * communications software * access to an ISP (Internet Service Provider) For a monthly payment anyone can connect to the Internet via an ISP. ...read more.


When the World Wide Web began in 1990, few people suspected how successful and popular it would be. There are now millions of websites with over one billion web pages. The incubator for some of the emerging technologies that will shape the future is known as Internet2. Internet was formed in 1996 and administered by the University Corporation for Advanced Internet Development (UCAID); Internet2 is a partnership of universities, corporations and government agencies. The project's goals are to create new applications that can't run over the existing Internet and to develop the infrastructure that supports those applications. Internet2 is not a single network, but a consortium of hundreds of high-speed networks linked by fibre optic backbones that span the U.S. It transmits data 45,000 times faster than a 56-k modem, allowing scientists to test their laboratory discoveries in the real world. While computers are now the primary means of accessing the Internet, we are already seeing many Internet-enabled devices, such as pagers and mobile phones, which can send and receive email and access the web. Soon everything from your car to your refrigerator may be connected to the network, communicating with each other wirelessly. 1 1 ...read more.
