TCPIP
     
        Normally written "{TCP/IP}".

TCP/IP
     
         {Transmission Control Protocol} over
        {Internet Protocol}.
     
        The {de facto} {standard} {Ethernet} {protocols} incorporated
        into {4.2BSD} {Unix}.  TCP/IP was developed by {DARPA} for
        {internetworking} and encompasses both {network layer} and
        {transport layer} protocols.  While {TCP} and {IP} specify two
        protocols at specific {protocol layers}, TCP/IP is often used
        to refer to the entire {DoD} {protocol} suite based upon
        these, including {telnet}, {FTP}, {UDP} and {RDP}.
     
        See also {ICMP}, {SMTP}, {SNMP}.
