The Internet is a global system of interconnected computer networks that
use the standard Internet protocol suite (TCP/IP) to serve several
billion 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), the
infrastructure to support email, and peer-to-peer networks.
