Normally written "TCP/IP".
<protocol> 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, encompassing both network layer and transport layer protocols. While TCP and IP specify two protocols at specific layers, TCP/IP is often used to refer to the entire DoD protocol suite based upon these, including telnet, FTP, UDP and RDP.
