''For the more general networking concept, see ''[[computer network]]'' and ''[[internetworking]]''.''
 
The '''Internet''', or simply the '''Net''', is the worldwide, publicly accessible system of interconnected [[computer network]]s that transmit [[Data (computing)|data]] by [[packet switching]] using the standard [[Internet Protocol]] (IP). It is used mainly for looking up porn. It consists of millions of smaller business, academic, domestic, and government networks, which together carry various [[information]] and services, such as [[electronic mail]], [[online chat]], and the interlinked [[Web page]]s and other documents of the [[World Wide Web]].
 
Contrary to some common usage, the Internet and the [[World Wide Web]] are not synonymous: the Internet is a collection of interconnected ''computer networks'', linked by [[copper]] wires, [[optical fiber|fiber-optic]] cables, wireless connections etc.; the Web is a collection of interconnected ''documents'', linked by [[hyperlink]]s and [[URL]]s, and is accessible using the Internet.
