rotocol. It is a communications protocol that uses the Internet Protocol
(IP) to exchange the messages between computers.
The TCP protocol guarantees reliable and in-order delivery of data from sender to receiver and distinguishes data for
multiple connections by concurrent applications (for example, Web server and e-mail server) running on the same
host.
The applications on networked hosts can use TCP to create connections to one another. It is known as a
connection-oriented protocol, which means that a connection is established and maintained until such time as the
message or messages to be exchanged by the application programs at each end have been exchanged. TCP is
responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets
back into the complete message at the other end.
Common network applications that use TCP include the World Wide Web (WWW), e-mail, and File Transfer Protocol
(FTP).
