A URL is an acronym (and an anglicism from information technology) that refers to the network address where some computer resource is located, such as a computer file or a peripheral device (printer, multifunction device, network drive, etc.).

This network could be the Internet , a corporate network (such as an intranet), etc.

It is a string sent to the server so that it is possible to filter or even create the resource.

The scheme tells the computer how to connect (what language the computer should use for communication), the domain specifies where to connect (the location of the other computer), and the remaining URL elements specify what is being requested.

Example: http://www.w3.org/Addressing/URL/uri-spec.html

In the example above, the protocol is HTTP, the server is designated as www.w3.org, and the resource (in this case, the uri-spec.html file) is located in Addressing/URL/.

The port, which is omitted, falls under the protocol default (in this case, port 80), and there is no query string or fragment identifier.
