Uniform Resource Locator (URL)

---

A Uniform Resource Locator (URL) is the address of a resource accessible on the Internet. URLs are the most commonly used form of Uniform Resource Identifier (URI). Many different types of resource are capable of being transferred and displayed by Internet protocols. When the World Wide Web's protocol (the Hypertext Transfer Protocol, or HTTP) is used, the resource can be an HTML page, an image file, a program such as a CGI application or Java applet, or any other file supported by HTTP. The URL contains the name of the protocol required to access the resource, a domain name that identifies a specific server on the Internet, and a hierarchical description of a file location on the server.
