The Internet protocol suite is the set of communications protocols that implements the protocol stack on which the Internet and many commercial networks run. It is part of the TCP/IP protocol suite, which is named after two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were also the first two networking protocols defined. A review of TCP/IP is given under that heading. Note that today's TCP/IP networking represents a synthesis of two developments that began in the 1970's, namely LAN's (Local Area Networks) and the Internet, both of which have revolutionized computing.
