underlined words or bordered graphics that have
web addresses embedded in them.
By clicking a hyperlink, you jump to a particular
page in a particular web site. You can easily
identify a hyperlink. Hypertext links are of different
colour from the rest of the text in a web site.

different web pages. As you surf around the web,
