World Wide Web

The World Wide Web (often referred to as the WWW or Web for short) is an extremely large hypertext system which is the most-popular application on the Internet (to the point that to many ordinary people, the two are synonyms). It consists of a large number of servers, which provide the content, along with the user applications, called 'browsers', which retrieve and display the content, usually on a personal computer of some sort.

The content is divided into 'static' content (which is stored in its final form, ready to be passed out to whoever asks for it), and 'dynamic', which is prepared in response to a user's request.
