   The HyperText Transfer Protocol (HTTP) that forms the basis of the World Wide Web uses URIs (Uniform Resource

 

Identifiers) to locate data on the Internet. URIs frequently are called URLs (Uniform Resource Locators). Actually, a URL

 

is a type of URI. Common URIs refer to files or directories and can reference objects that perform complex tasks, such as

 

database lookups and Internet searches. If you know the URI of publicly available HTML files anywhere on the World

 

Wide Web, you can access that data through HTTP.

 

 

   A URI is a purely syntactical construct that specifies the various parts of the string specifying a web resource. A URL is

 

a special kind of URI, namely, one with sufficient information to locate a resource.
