TCP/IP

Short for Transmission Control Protocol/Internet Protocol, TCP/IP also commonly abbreviated as TCP was developed in 1978 and driven by Bob Kahn and Vint Cerf. Today, TCP/IP is a language governing communications among all computers on the Internet.

TCP/IP is two separate protocols, TCP and IP, that are used together. The Internet Protocol standard dictates how packets of information are sent out over networks. IP has a packet-addressing method that lets any computer on the Internet forward a packet to another computer that is a step (or more) closer to the packet's recipient. The Transmission Control Protocol ensures the reliability of data transmission across Internet connected networks. TCP checks packets for errors and submits requests for re-transmissions if errors are found.
