TCP/IP |
|
Transmission Control Protocol/Internet Protocol is a set of networking protocols developed in the 1970s. TCP/IP includes Transport Control Protocol, which is a connection-oriented transport protocol that includes transport, session, and presentation layer protocol functions, which is equivalent to layers 4, 5, and 6 of the OSI Model and Internet Protocol, and a widely used routable network protocol that corresponds to layer 3 of the OSI model. User Datagram Protocol (UDP) can be substituted in cases where connectionless datagram service is desired. TCP/IP is an entire protocol stack that includes protocols for file transfers (FTP), termination emulation services (telnet), electronic mail (SMTP), address resolution (ARP and RARP), and error control and notification (ICMP and SNMP). TCP/IP is used extensively in many computer systems because it is nonproprietary--free from royalties. Its use was mandated by Congress for use in computer systems for many government agencies and contract situations. TCP/IP is also used in the Internet, a huge government and research internetwork spanning North America and much of the world. TCP/IP is the most commonly used set of network protocols. |
