Transmission Control Protocol/Internet Protocol (TCP/IP) is a low-level communications protocol used to connect hosts on the Internet or a network. TCP/IP connections are established between clients and servers via sockets. TCP/IP is stream-oriented meaning it deposits bits in one end and they show up at the other end.

TCP/IP Basics:

  • Socket is “communication endpoint”
  • Server = wait for connection
  • Client = initiate connection
  • Sequenced, reliable transport
  • Bi-directional by definition
  • Sometimes/often used uni-directionally

    Synonyms: Transmission Control Protocol/Internet Protocol
