The Internet
The Internet is a global system of interconnected computer networks that serves billions of users worldwide. It is an abbreviation of the term Interconnected Network.

It is made up of a network of networks that consists of millions of private and public, academic, business, and government computers many of them on networks of their own, some like, private computers can be a single computer and its only connection is to the Internet.
They are all linked together by almost any means of networking technology ranging from dialup, broadband, wireless and optical networking to name but a few.

The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.So the terms Internet and World Wide Web which are often used in everyday speech without much distinction should not be confused as they are quite different and when people refer to the 'Net' they really mean the WWW as they are talking about the data and information resources.

The Internet is also often simply referred to as the net. In many technical illustrations when the precise location of Internet resources is not important, the Internet is often referred as the cloud, and is shown as a cloud. Increasingly, you will find services referred to as "cloud computing" which means that the computer and software are located somewhere on the Internet rather than on your local computer.
