Detailed explanation-1: -Which transport layer feature is used to establish a connection-oriented session? TCP uses the 3-way handshake. UDP does not use this feature. The 3-way handshake ensures there is connectivity between the source and destination devices before transmission occurs.
Detailed explanation-2: -It passes a connection request to TCP which lives at Layer 4 of the OSI model, the Transport layer. The TCP handler receives the connection request. Then, it creates a packet with the “SYN” flag set-the first part of the three-way handshake with the remote server to establish a connection.
Detailed explanation-3: -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.
