uniform resource locator

A sequence of characters that represent information resources on a computer or in a network such as the Internet or company Intranet. This sequence of characters includes:
- The abbreviated name of the protocol used to access the information resource; and
- The information used by the protocol to locate the information resource.
For example, in the context of the Internet, these are abbreviated names of some protocols used to access various information resources: http, ftp, gopher, telnet, and news; and this is the URL for the IBM home page: http://www.ibm.com/. Note that you will be able to use this link only if you are able to access the World Wide Web.
The address of an item on the World Wide Web. It includes the protocol followed by the fully qualified domain name (sometimes called the host name) and the request. The Web server typically maps the request portion of the URL to a path and file name. For example, if the URL is http://www.networking.ibm.com/nsg/nsgmain.htm, the protocol is http; the fully qualified domain name is www.networking.ibm.com; and the request is /nsg/nsgmain.htm.
