Detailed explanation-1: -Which transport layer feature is used to guarantee session establishment? Explanation: 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: -FTP and HTTP require the use of the TCP transport layer protocol.
Detailed explanation-3: -The basic function of the Transport layer is to accept data from the session layer, split it up into smaller units if need be, pass these to the Network layer, and ensure that all the pieces arrive correctly at the other end.
Detailed explanation-4: -The transport layer is responsible for flow control. It uses the sliding window protocol that makes the data transmission more efficient as well as it controls the flow of data so that the receiver does not become overwhelmed. Sliding window protocol is byte oriented rather than frame oriented.
