Transmission Control 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 {reliable
        communication} 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.
