Uniform resource locator

The address of a website, a type of Uniform resource identifier (URI).

The address of a file (or 'resource') accessible on the internet. The type of resource depends on the internet application protocol (such as HTTP or FTP). Using the web's Hypertext Transfer Protocol, the resource can be an HTML page, an image file, a program, 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 computer on the Internet, and a hierarchical description of a file location on the computer.
