Anatomy of a URL (Universal Resource :Locater)

The URL is a combination of five elements: protocol, separators, domain name, sub directories, and the document name

http:          protocol
     //             separators
     www.cnn.com/   domain name
     news/       subdirectory name
     today.html    document name (Web page)
