Transmission Control Protocol

networking, protocol (TCP) The most common transport layer

protocol used on Ethernet and the Internet. It was

developed by DARPA.

TCP is the connection-oriented protocol built on top of

Internet Protocol (IP) and is nearly always seen in the

combination TCP/IP (TCP over IP). It adds reliablecommunication and flow-control and provides full-duplex,

process-to-process connections.

TCP is defined in STD 7 and RFC 793.

User Datagram Protocol is the other, connectionless,

protocol that runs on top of IP.
