Answer the questions below with reference to Data Link Layer (max 250 words):

i) A local Area Network (LAN) Medium Access Control (MAC) protocol aims to achieve fair and efficient access to a LAN transmission medium. Characterise the distinction between authorisation based (“taking turns”) and contention based (random access) MAC layer protocols and discuss the suitability of each protocol in light traffic and heavy traffic networks in terms of fairness and efficiency of access.

ii) In CSMA/CD, after the fifth collision, what is the probability that a node chooses k=4. The result k=4 corresponds to a delay of how many seconds on a 10Mbps Ethernet?
