In computing, a Uniform Resource Identifier (URI) is a string of characters used to identify a name]] of a resource.

Description

Such identification enables interaction with representations of the resource over a network, typically the World Wide Web, using specific protocols.

Schemes specifying a concrete syntax and associated protocols define each URI.

URL

The most common form of URI is the Uniform Resource Locator (URL), frequently referred to informally as a web address.

URN

More rarely seen in usage is the Uniform Resource Name (URN), which was designed to complement URLs by providing a mechanism for the identification of resources in particular namespaces.
