URL

A generalization of the file naming concepts already in common use on the Internet. A URL extends the filename and pathname used to refer to files on a computer by adding an Internet address and protocol component. A URL specifies the computer and access method (protocol) in addition to the filename and thus can be used to refer to files anywhere on a network.

While URLs are used in various forms by different systems, they are most closely associated with the World Wide Web.
