Uniform resource locator (URL)

A website address, using a universally recognized method of naming websites. It is also called IP address (Internet protocol) and domain name. This is a clever categorization scheme similar to area codes, that help computer users find other computers on the Internet network.. URLs are actually numbers, but because users can more easily remember names, a domain name server translates back and forth. A URL consists of four levels. These are: (1) Hypertext protocol (http://), (2) World wide web (WWW), (3) Second level domain (Yahoo!), and (4) Top-level domain (com).
