Description
TCP/IP
The two best-known internet protocols, often erroneously thought of as one protocol—The Transmission
Control Protocol (TCP), which corresponds to Layer 4 (the transport layer) of the Open System
Interconnection (OSI) reference model, provides reliable transmission of data. The Internet Protocol (IP)
corresponds to Layer 3 (the network layer) of the OSI reference model and provides connectionless
datagram service. TCP/IP were the internetworking protocols developed by the U.S. Department of
Defense's Advanced Research Project Agency (ARPA) in the 1970s to support the construction of
worldwide internetworks. TCP/IP has been widely adopted and supported by computer and software
manufacturers as a standard computer networking protocol. It is a transport and interworking protocol
that is an accepted networking standard. Commonly used over X.25 and Ethernet cabling, TCP/IP is
viewed as one of the few protocols available that is able to offer a true migration path toward OSI. It was
originally developed by the U.S. Department of Defense and is able to operate in most environments.
TCP/IP operates as Layers 3 and 4 of the OSI model (network and transport, respectively). TCP/IP
ensures that packets of data are delivered to their destination in the sequence in which they were
transmitted. TCP/IP is also the delivery mechanism for associated services, including Simple Network
Management Protocol (SNMP), Simple Mail Transfer Protocol (SMTP), File Transfer Protocol (FTP),
and Telnet. TCP/IP protocols are the WAN protocols of choice. They include protocols that address
media access, packet transport, session communication, file transfer, electronic mail, and terminal
emulation. The main protocols in the suite include the following:

TCP is the reliable end-to-end protocol used on the Internet. It is a virtual circuit protocol in that when a
connection is established between two endpoints, data flows only between those two endpoints until the
connection is closed. TCP is defined in RFC-793. TCP and IP are the two best-known protocols in the
suite. See also TCP/IP and IP.
