World Wide Web (www)
A hypertext-based system of servers on the Internet. Hypertext is data that contains one or more links to other data; a link can point to many different types of resources including text, graphics, sound, animated files, a network newsgroup, a telnet session, an FTP session, or another web server. You use a special program called a "browser" (e.g., Firefox or Internet Explorer) for viewing World Wide Web pages. Also referred to as "WWW" or "the web".
