Uniform resource locator(URL)

A URL describes the location and a method of accessing a resource on  the internet.  For example, the URL "http://www.adobe.com" may lead you to the home page of the company called Adobe Corporation, makers of various publishing software like page Maker, etc.  Each URL is unique .  It identifies a particular point on the Internet.  It consists of a string that supplies the Internet address of a resource on the WWW along with the protocol by which the resource is accessed.  The most common URL types are 'gopher' which gives the Internet address of a Gopher directory, and 'FTP' which gives the address of a FTP resource.  All Web sites have URLs.  One could say a URL is what a telephone number is to a telephone or a street address is to a house.
