Explanation:
Detailed explanation-1: -Data-Link Layer–Framing Takes Place Data-link layer protocols, such as PPP, format the IP datagram into a frame. They attach a third header and a footer to “frame” the datagram. The frame header includes a cyclical redundancy check (CRC) field that checks for errors as the frame travels over the network media.
Detailed explanation-2: -The data link layer takes the packet from the network layer and breaks it into frames. The header in this layer provides the source and destination MAC addresses. It is the data link layer that will convert the data into binary digits such as 1 and 0 and then prepare them for the physical layer.
