Problem
Assume you need to explain to a new and inexperienced trainee the main differences between the Medium Access Control PDU standards through one example where an IP datagram has been passed down to the data link layer. Describe the MAC PDUs for both standards, make sure you indicate the information that an IP datagram is to be delivered to the next hop's network layer.
Note: In your explanation, you need to cover the differences of frame structure and the data link layer itself for both standards. Also make sure you explicitly show where the information about the IP protocol will be indicated in the PDU structure of the data link layer in each standard. Besides explanations, you can complement your answer by drawing your example digitally or by hand and incorporating it to your answer as a figure.
