In the general sense, an internet (with a lowercase "i", a shortened form of the original inter-network) is a computer network that connects several networks. As a proper noun, the Internet is the publicly available internationally interconnected system of computers (plus the information and services they provide to their users) that uses the TCP/IP suite of packet switching communications protocols. Thus, the largest internet is called simply "the" Internet. The art of connecting networks in this way is called internetworking.
