TCP (Transmission Control Protocol) A method used along with the Internet Protocol
(IP) to send data in the form of message units between computers over the Internet. IP
takes care of handling the actual delivery of the data, and TCP takes care of keeping
track of the individual units of data (called packets) into which a message is divided for
efficient routing through the Internet.
