TCP/IP Protocol Architecture. TCP/IP protocols map to a four-layer conceptual model known as the DARPA model , named after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet, and Network Interface. Each layer in the DARPA model corresponds to one or more layers of the seven-layer Open Systems Interconnection (OSI) model. Figure 1.1 shows the TCP/IP protocol architecture. Figure 1.1 TCP/IP Protocol Architecture. Network Interface Layer
TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, manages the assembling of a message or file into smaller packet s that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message.CP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet).
