Uniform Resource Identifier (URI) Glossary Definition

A Uniform Resource Identifier (URI) is a string of characters that are used to identify the name of a resource. Such identification enables interaction with representations of the resource over a network (such as the World Wide Web) using specific protocols. In other word, URI is the generic term for all types of names and addresses that refer to objects on the World Wide Web.

This term is commonly used in software engineering, programming, scripting, application design, testing, and development lifecycle work.

Site owners, developers, writers, and administrators use this concept when planning navigation, publishing links, configuring domains, or diagnosing access problems.

Related concepts include Domain Name System, Uniform Resource Locator and Internet Protocol.
