THE INTERNET AND THE WORLD WIDE WEB


THE INTERNET AND THE WORLD WIDE WEB

The Internet, which has come to serve over 20 million users worldwide, had relatively humble beginnings. It began as a rather obscure network called ARPANET-a network used by the Department of Defense, its contractors, and defense researchers. The ARPANET proved very useful and powerful, so much so that over time it grew tremendously, Soon, a more general network called the Internet was created with the same philosophy as ARPANET, only with a broader scope. In the late 19805, the Internet spread across universities around the world and became more and more popular among researchers in the academic community.
As the popularity of the Internet increased, so did it's size. Starting in its earlier days, users became increasingly aware of the benefits of specific services such as electronic mail and the ability to transfer files. Over time, the incredible potential of the Internet for sharing and distributing information became apparent as more and more people started using it.
The National Science Foundation, which had almost completely funded the Internet in the United States until 1991, lined its ban of commercial traffic on the Internet in I99] and dropped most of its funding. This gave the Internet much more widespread exposure and opened the door to many more
commercial ventures. Since then, the Internet has grown in incredible proportions.
How do people use the Internet? The internet is used for sending and receiving electronic mail, exchanging files, reading and participating in news groups, and obtaining information in general. You can browse a Web page filled with information on a computer network or participate in a news group discussion of wildlife. You might find a reference to a public file containing research on wildlife and then download the file to your computer. You could even send an e-mail to the President of the World Wildlife Federation, given the correct address.
The best way to describe the internet is to list the services it provides. The Internet has a wide variety of services available to the user. Often, a service on the Internet is called a protocol. A protocol is simply a set of rules for communication. Each service has its own special set of rules to accomplish
its goals more easily. The following list describes some of the major services:
