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.
