The
Internet is the global system of interconnected
computer networks that use the
Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a
network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, 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 and
applications of the
World Wide Web (WWW),
electronic mail,
telephony, and
peer-to-peer networks for
file sharing.
