Internet


The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide.



                                                                                   It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. 


               
         The Internet carries an extensive range of information resources and services,such as the inter-linked hypertext documents of the      World Wide Web (WWW)  and the infrastructure to support email.
