The World-Wide Web (WWW, W3, or simply the Web) is a universe of on-line information which is available on the Internet. Developed at CERN (Conseil Europeen pour la Recherche Nucleaire: the European Laboratory for Particle Physics), the World-Wide Web project provides a distirbuted information delivery system using hypertext and hypermedia.
Reading a document containing hypertext is like reading any other document, except that you can access links (areas of the document which point to other documents) that have been placed in the document by its author. These links point to other documents, perhaps written by other authors, located on computers all over the Internet. Hypermedia is similar to hypertext except that the links are not limited to text, but can also be images, sound, and animations.
In order to read a hypertext document, you use a Browser. It is the job of the browser to access the document and present it to you on a display device (such as a terminal or computer monitor). Some common browsers are Mosaic, Netscape and Internet Explorer. Note that some browsers, such as LYNX, are text-only browsers and cannot display images, sounds, or animations.
In order to publish information on the World-Wide Web, you must have access to an HTTP (HyperText Trasnport Protocol) Server (often called a Web Server). Using special codes, called HTML (HyperText Markup Language), you can create documents suitable for publishing on the Web.
