What is World Wide Web?

       The World Wide Web (WWW), or W3 or commonly known as The
Web, consists of a worldwide collection of electronic documents. Each
electronic document on the Web is called a Web page, which can contain
text, graphics, animation, audio, and video.

      Additionally, Web pages usually have built-in connections to other
documents. The World Wide Web is a system of interlinked hypertext
documents accessed via the Internet. With a web browser, one can view
web pages that may contain text, images, videos, and other multimedia and
navigate between them via hyperlinks.

Navigating Web Pages

       Most Web pages contain hypertext or hypermedia links. Hypertext
refers to links in text-based documents, whereas hypermedia combines text-
based links with graphic, audio, and video links. Links allow you to obtain
information in a nonlinear way. That is, instead of accessing topics in a
specified order, you move directly to a topic of interest. Branching from one
related topic to another in a nonlinear fashion is what makes links so
powerful. Some people use the phrase, surfing the Web, to refer to the
activity of using links to explore the Web.

      A link can be text or an image. Text links may be underlined and/or
displayed in a color different from other text on the Web page. Pointing to,
or positioning the pointer on, a link on the screen typically changes the
shape of the pointer to a small hand with a pointing index finger. Pointing to
a link also sometimes causes the link to change in appearance or play a
sound. For example, an underline may disappear, the text may change color,
the image may change, etc. Each link on a Web page corresponds to a Web
address or a document. To activate a link, you click it, that is, point to the
link and then press the left mouse button. Clicking a link causes the Web
page or document associated with the link to be displayed on the screen.

       The linked object might be on the same Web page, a different Web
page at the same Web site, or a separate Web page at a different Web site
in another city or country. To remind you visually that you have clicked a
link, a text link often changes color after you click it.

      Most current Web browsers support tabbed browsing, where the top
of the browser displays a tab (similar to a file folder tab) for each Web page
you open. To move from one open Web page to another, you click the tab in
the Web browser. Tabbed browsing allows users to have multiple home
pages that automatically open when the browser starts. You also can
organize tabs in a group, called a tab group, and save the group as a
favorite, so that at any time you can display all tabs at once. Because some
Web sites attempt to track your browsing habits or gather personal
information, some current Web browsers include a feature that allows you
to disable and/or more tightly control the dissemination of your browsing
habits and personal information.
