The Internet consists of all computers and networks across the world which are able to communicate with each other using telephone, fibre optic, microwave, radio, satellite or any other type of link. The Internet includes private, commercial, government and military computer systems. The main links which join continents, countries and major cities are collectively called the Internet Backbone.

Computers on the Internet use specific rules, called protocols, that define the procedures for communication. The protocol that controls communication across the Internet is called TCP/IP or Transmission Control Protocol / Internet Protocol.
The World Wide Web or WWW is part of the Internet. This consists of servers that store web pages which can be read by browsers such as Mozilla, Netscape, Opera or Internet Explorer. Web pages in turn have a specific format known as HTML or Hypertext

Markup Language. A browser is an application that is able to read (but not create) web pages.
