A URL is a Uniform Resource Locator, and is a reference to a resource on the Internet.

You have used URLs to find web pages in your Internet web browser. For example, here is the URL used to access the JavaSoft home page:

http://www.javasoft.com/

The parts of this URL are as follows:

• http is the Protocol Identifier -- in this case, identifying the HTTP protocol.
• : (colon) separates the Protocol Identifier from the Resource Name
• www.javasoft.com/ is the Resource Name -- in this case, identifying the host name www.javasoft.com
