What is URL ? What is WWW ?

A URL (Uniform Resource Locator) specifies the distinct address for each resource on the Internet. Each website on the internet has a unique URL. The format of URL is as follows:

type://address/path

where, 'type' specifies the type of server in which the file is located, 'address' is the address of server, and 'path' tells the location of file on the server.

An example of URL is http://encycle.msn.com/getinfo/styles.asp

The World Wide Web (WWW) is a set of protocols that allows us to access any document on the internet through a naming system based on uniform resource locators (URLs).
