A Uniform Resource Identifier (URI), formerly Universal Resource Identifier, is a unique sequence of characters that identifies an abstract or physical resource, such as resources on a webpage, email address, phone number, books, real-world objects such as people and places, and concepts. In particular, the resource need not be retrievable via the Internet, or any computer network.
URIs that provide a means of locating and retrieving information resources on a network (like the Internet, an Intranet or a computer file system) are called Uniform Resource Locators (URLs). URLs are therefore a subset of URIs. Other URIs provide only a unique name, without a means of locating or retrieving the resource or information about it; these are Uniform Resource Names (URNs). The web technologies that use URIs are not limited to web browsers.
