Transmission Control Protocol/Internet Protocol(TCP/IP)
TCP/IP is a two-layered program. The lower layer, the Internet Protocol, sets the basic rules by which data is sent from one computer to another. To facilitate sending and receiving, messages are divided into little chunks called packets. The higher layer, the Transmission Control Protocol (TCP
), is a set of rules used along with the Internet Protocol. While the Internet Protocol handles the actual delivery of the data, the Transmission Control Protocol keeps track of the individual packets for efficient routing through the Internet. The Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication protocol of the Internet. It can also be used as a communications protocol in private networks (or intranets). A computer set up with direct access to the Internet uses the TCP/IP protocol to send and receive data.
