TCP/IP is the basic communication language or protocol of the Internet. TCP/IP uses the client/server model of communication.
TCP/IP is a two-layer program. The higher layer Transmission Control Protocol, manages the assembling of a message or file into smaller packets that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination.
