1) What are the two sublayers of the Data Link Layer? Describe the function of each and their position relative to one another. 2) Describe each of the following media access methods: Polling Token Passing Contention 3) Which of the above media access methods would be LEAST efficient in a very busy network. Explain your answer. 4) a) List two hardware devices that are associated with the Data Link layer. b) Which is the most commonly used in modern Ethernet networks? 5) Explain how CSMA/CD works. 6) Look at the Ethernet frame. Based on the size of the field that holds the MAC address, how long is a MAC address? 7) What is the function of the last field in an Ethernet frame? 8) List two LAN types other than Ethernet, (Ethernet being by far the most popular LAN type). 9) Provide an example of an Ethernet MAC address. 1) What are the two sublayers of the Data Link Layer?
