Detailed explanation-1: -The network layer adds a header to the packet which includes the logical addresses of both the sender and the receiver. Internetworking: This is the main role of the network layer that it provides the logical connection between different types of networks.
Detailed explanation-2: -Internet Layer reads information in the header to identify the transmission and determine if it is a fragment. If the transmission was fragmented, IP reassembles the fragments into the original datagram. It then strips off the IP header and passes the datagram on to transport layer protocols.
Detailed explanation-3: -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-4: -Network layer: Handles the routing and sending of data between different networks.
