Detailed explanation-1: -TCP is an example of a connection-oriented protocol. It requires a logical connection to be established between the two processes before data is exchanged. The connection must be maintained during the entire time that communication is taking place, then released afterwards.
Detailed explanation-2: -In terms of the OSI model, TCP is a transport-layer protocol. It provides a connection-oriented data transmission service between applications, that is, a connection is established before data transmission begins.
Detailed explanation-3: -TCP is connection-oriented because before one application process can begin to send data to another, the two processes must first “handshake” with each other–that is, they must send some preliminary segments to each other to establish the parameters of the ensuing data transfer.
Detailed explanation-4: -In fact, the two protocols most commonly associated with the Transport layer are defined by their connection state: The Transmission Control Protocol (TCP) is connection-oriented, whereas the User Datagram Protocol (UDP) is connectionless.
