Although the terms Web and Internet are often used interchangeably, they are really two different things. The Internet refers to the physical side of an immense global computer network. The World Wide Web is a way of communicating text, graphics and multimedia over the Internet.
The Internet is a worldwide group of public and private computers linked together to exchange information. The Internet evolved out of a group of corporations, governments, universities and research groups that started networking their computers in the 1970's (the first of these networks was established 25 years ago by the United States Department of Defense). Then, as now, the main purpose of the Internet was to share information. No one owns the Internet, nor is it controlled or regulated by anyone. It is a true universal, shared resource.

The Internet offers a variety of services. The two most popular are the World Wide Web (WWW) and electronic mail (email). Other commonly-used services include social networks, file downloads, and searching. The list continues to grow quickly as the Internet becomes more and more an integral part of daily life.
The World Wide Web is a collection of electronically linked documents that are stored on the Internet. When you use the web, you look for and retrieve Internet information using a click and point graphical interface. The documents are formatted in a language called HTML. (Hypertext Markup Language) that supports links to other documents.
A file that you request on the World Wide Web is called a web page. The pages are made up of text, images, animation, sound files, videos, virtual reality, programs and data. A web site is a collection of web pages. A homepage is your entry point into a web site. The World Wide Web is often abbreviated as the Web, WWW or W3.
