Introduction


Origin of the WWW

The Worl Wide Web was founded in 1989 by Timothy Berners-Lee and other researchers at the CERN research facility near Geneva, Switzerland.

The objectives of the WWW was to make it easy for researchers to share data with minimum training and support.

The World Wide Web is based on a system of hypertext documents that contain elements known as links that you can select, usually by clicking the mouse, to move to another part of the same document or to a new document.  The documents referenced by links can be located anywhere on the Internet.

Each hypertext document on the Web is called a Web Page and is stored  on a computer on the Internet called a Web Server.  A Web page can contain links to other Web pages located  anywhere on the Internet.  The ability to cross-reference other Web pages with links is a key feature of the Web.

Examples:
