The internet is a system architecture that allows computer networks around the world run by public and private sector organizations to connect each other.

The result is a mass of various transmission cables, computers, data centres, routers, servers and satellites that allows digital information to travel around the world. It uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. HTTP is the primary transport protocol of the Web, while HTML defines the organization and structure of the Web documents to be exchanged.

The Internet can be used for almost any purpose that depends on information, and it is accessible by every individual who connects to one of its constituent networks. The Internet supports access to digital information by many applications, including the World Wide Web (WWW).
