A system of
Internet servers that support specially
formatted documents. The documents are
formatted in a markup language called HTML (HyperText
Markup Language) that supports links to
other documents, as well as graphics, audio,
and video files. This means you can jump
from one document to another simply by
clicking on hot spots. Not all Internet
servers are part of the World Wide Web.
There are several applications called Web browsers that make it easy to access the World Wide Web; Two of the most popular being Netscape Navigator and Microsoft's Internet Explorer.
World Wide Web is not synonymous with the Internet.
