What
is the World Wide Web?
The World Wide Web
(WWW) is a service used to access information over the Internet. The
World Wide Web was developed in order to incorporate many different
media including text, graphics, sound, and video. The Web has become
very popular because of these different media and because it is a hypertext
system which is easy to use.
What
is Hypertext?
Hypertext allows
the user to move from one page to the next on the Web by clicking on
highlighted links or underlined terms. Hypertext is structured to follow
a train of thought and direct it to related topics of interest. Most
documents on the World Wide Web were created using HTML or Hypertext
Markup Language. These documents are often referred to as Web Sites,
Web pages, or home pages.
WWW
Browsers
Browsers are used to display
the information on the World Wide Web. Netscape and Microsoft Explorer
are graphical browsers which display images and sound as well as text.
Through your e-mail account you may access Lynx a Web browser
which displays text but not sounds or images.
