TCP (Transmission Control Protocol) A higher-level protocol than IP, it provides continuing connections between programs. TCP also makes IP datagrams smaller and faster. TCP divides datagrams into smaller segments to fit the physical requirements of the servers on the network. It then uses IP to transmit the segments of data.

TCP/IP (Transmission Control Protocol/Internet Protocol) A network protocol used on the Internet and on local area networks. TCP/IP is a set of communications protocols supported by various manufacturers and vendors. Corporations, universities, and other agencies use TCP/IP to communicate over the Internet.
