World Wide Web
§Created in 1989 by Tim Berners-Lee and his colleagues at CERN, a physics laboratory in Switzerland

§Their goal was to provide shared documents and graphics more easily on the Internet
The WWW is the whole constellation of Internet resources.  It provides the protocol for text files and multi-media.  What the WWW can do which none of the other Internet modes can is handle "hypermedia" such as graphics, moving and still images, audio, real-time chat or sound, etc.  The WWW uses the hypertext transfer protocol (http) to enable sounds, images, text, etc. to be mixed together in the same documents.  Although most WWW documents are written in the html (hypertext markup language), gopher and ftp sites can also be accessed via the WWW.  The WWW also allows any computer to become a client, and any computer to become a server.  Plus, the WWW allows different kinds of machines to communicate with eachother by providing a simple, common language (via the browser).
