Explanation:
Transport layer is responsible for overall “end-to-end” communication. It provides communication service to the application process which might be running on “different hosts”.
TCP (Transmission Control Protocol) or UDP (User Data Protocol) is the protocol used in the Transport layer. The port number is essential so that the transport layer can carry packets to the right destination pointing to the right application.
