Links
It is the hyperlinks between Web pages that form the web-like structure of the Web. In the picture, each rectangle represents a Web page. Each arrow represents a link:
The "links" between pages are not physical links
(i.e. they are not physical wires or any other sort of direct connection).
A link is established from one page to another when the
first page includes the "address" of the second page.
This is done
with the anchor tag.
For example,
the following might be the tag in PageA.html
to link it to PageB.html if both pages were in the
same directory on the same hard disk:
<a href="PageB.html"> Click Here to go to Page B </a>
A Web address is called a URL for Uniform Resource Locator. If a Web page links to a page on a different computer a full URL must be used. For the moment, assume that the pages in the picture all reside in the same disk directory (so the file name alone will work as a web address.)
