Once a small and simple collection of computers run by the Defence Department, is now a massive world wide network of computers, what we call the 'Internet'. The word "Internet" literally means "network of networks." In itself, the Internet is composed of thousands of smaller local networks scattered throughout the globe. It connects roughly 15 million users in more than 50 countries a day. The World Wide Web (WWW) is mostly used on the Internet. The Web refers to a body of information, while the Internet refers to the physical side of the global network containing a large amount of cables and computers. The Internet is a 'packet-switching' computer network. When a person sends a message over the Internet, it is broken into tiny pieces, called 'packets'. These packets travel over many different routes between the computer that it is being sent from to the computer to which it is being sent to. Phone lines, either fibre-optics or copper wires ones, carry most of the data packets. Internet computers along the path switch each packet that will take it to its destination, but no two packets need to follow the same path. The Internet is designed so that packets always take the best available route at the time they are tr
All Web clients and servers must be able to speak HTTP to send and receive hypermedia documents. Another formatting language used for Web documents is 'Standard Generalized Markup Language' (SGML). The packets are all switched into a destination and reassembled by the desti!nation computer. The process of how this work is very simple, one example is; Running a Web browser, the user selects a piece of hypertext connected to another text -"Planes. Every packet is written in a particular protocol language, called TCP/IP, which stands for Transmission Control Protocol/Internetworking Protocol. The amount of people connecting to the Internet is growing at a rapid rate, along with the number of "host" machines with direct connection to TCPIP. John Quarterman, The Matrix: Computer Networks and Conferencing Systems Worldwide (Bedford, MA: Digital Press, 1990), 42. This is just like how certain city streets often run parrel to each other for many miles before reaching an intersection. Data packets travelling on a 'backbone' network stay within that network for much of their journey. A Web is a program running on a computer who's only purpose is to serve documents to other computers when asked. The packet-switching nature of the Internet gives it sufficient speed and flexibility to support real-time communication, such as sending messages to other people in a chat environment (IRC). HTML documents are nothing more than standard 7-bit ASCII files with formatting codes that contain information about the layout (text styles, document titles, paragraphs, lists and hyperlinks). It is spreading faster than cellular phones, and fax machines. There are six companies in the US with large, nationwide networks of high-speed phone lines and routers. ------------------------------------------------------------------------**Bibliography**.
