WordNet (r) 3.0 (2006):

TCP/IP
    n 1: a set of protocols (including TCP) developed for the
         internet in the 1970s to get data from one network device
         to another [syn: transmission control protocol/internet
         protocol, TCP/IP]

V.E.R.A. -- Virtual Entity of Relevant Acronyms (February 2016):

TCPIP
       Transmission Control Protocol/Internet Protocol (RFC 793, IP),
"TCP/IP"


The Jargon File (version 4.4.7, 29 Dec 2003):

TCP/IP
 /T'C?P I?P/, n.

    1. [Transmission Control Protocol/Internet Protocol] The
    wide-area-networking protocol that makes the Internet work, and the only
    one most hackers can speak the name of without laughing or retching. Unlike
    such allegedly ?standard? competitors such as X.25, DECnet, and the ISO
    7-layer stack, TCP/IP evolved primarily by actually being used, rather than
    being handed down from on high by a vendor or a heavily-politicized
    standards committee. Consequently, it (a) works, (b) actually promotes
    cheap cross-platform connectivity, and (c) annoys the hell out of corporate
    and governmental empire-builders everywhere. Hackers value all three of
    these properties. See creationism.

    2. [Amateur Packet Radio] Formerly expanded as ?The Crap Phil Is Pushing?.
    The reference is to Phil Karn, KA9Q, and the context was an ongoing
    technical/political war between the majority of sites still running AX.25
    and the TCP/IP relays. TCP/IP won.


The Free On-line Dictionary of Computing (30 December 2018):

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.
