Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The Transmission Control Protocol (TCP) is a transport protocol that is used on top of IP to ensure reliable transmission of packets.
Detailed explanation-3: -Roles of the Transport Layer The transport layer provides transparent transfer of data between end users, providing reli-able data transfer services to the upper layers. The transport layer controls the reliability of a given link through flow control, segmentation/desegmentation, and error control.
