FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The transport transport layer is responsible responsible for process-to-process delivery-the delivery of a packet, part of a message, from one process to another.

Detailed explanation-2: -Process to Process Communication Transport Layer uses a port number to deliver the segmented data to the correct process amongst the multiple processes that are running on a particular host. A port number is a 16-bit address used by transport layer to identify any client-server program.

Detailed explanation-3: -The transport layer controls the reliability of a given link through flow control, segmentation and desegmentation, and error control. Some protocols are state-and connection-oriented. This means that the transport layer can keep track of the segments and retransmit those that fail.

Detailed explanation-4: -Transport The fourth layer of the OSI model ensures complete and reliable delivery of data packets. The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of the data packets, check for errors and duplication, and resend the information that fails delivery.

Detailed explanation-5: -The data link layer is responsible for the node-to-node delivery of the message. The main function of this layer is to make sure data transfer is error-free from one node to another, over the physical layer.
