Explanation:
Detailed explanation-1: -In IPv4, each endpoint is identified by one or more gloablly unique IP addresses. The network layer PDUs are known as either “packets” or “datagrams". Each packet carries the source IP address of the sending endpoint and also the address of the intended recipient endpoint (or a group destination address).
Detailed explanation-2: -The data link layer takes the data bits and “frames, ‘’ and creates packets of the data to guarantee reliable transmission. This layer adds source and destination addresses to the data stream as well as information to detect and control transmission errors. The data link layer has two sublayers.
