The browser uses Internet addresses to locate the files needed to display the Web page on your computer. A web page may have more than one URL but a URL can only reference a single web page. The HTTP in the URL tells the server that the browser is requesting a hypertext document. The rest of the URL contains information on the server's domain, the directory to the file, and the name of the file to be displayed. Clues about where you are going and what type of file you are requesting can be gathered from the URL address.
