Hyperlinks

One Web page is connected to another with a hyperlink. If you have been reading these notes over the Web, you have been linking between Web pages by using hyperlinks.

A web browser (such as Netscape Navigator) usually displays a hyperlink in a distinguishing color (usually blue.) When you click on it, the browser asks the operating system of the computer to get a particular Web page from another computer connected to the Internet. The Web page to get is specified with a uniform resource locator URL. A URL specifies both the computer (among all the Internet computers in the world) and the exact Web page on that computer.

To see some examples of URLs, keep watching the box in your browser labeled "Location:"

QUESTION 15:

When you click on the following hyperlink, will the URL in the "Location:" box change?
