What is URl?

Answer 1

URI is an acronym for Universal Resource Identifier.

It is a standard for identifying a resource (site, name, application, etc.) across a computer network (the biggest example being the internet!)

A fully qualified Internet URI must include a protocol (e.g. HTTP), a server (e.g. wiki), a domain name (e.g. answers) and it's position within the DNS structure (e.g. com)

hence - http://wiki.answers.com/

This instructs the browser application to use the http protocol suite to communicate with the wiki server which is found in the answers domain of the .com portion of the DNS structure.

URL - Abbreviation of Uniform Resource Locator, the global address of documents and other resources on the World Wide Web.

The first part of the address is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes.

Uniform Resource Locator; an address that specifies the location of a file on the Internet (e.g., http://wiki.answers.com%29

Another example for URL or unifor resource locator is:

http://www.avnoy.com/alarm/flash.swf
