Hello,

Please support providing a solution for the below-mentioned question for understanding the concepts.

Q2. (a) Define what is mean by the term LAN and give 3 attributes that distinguish it from a WAN. (b) In relation to LANs, define the term MAC and explain its general role in network operation. Describe the role played by the IEEE in supporting MAC development. (c) What are the names by which IEEE MAC protocols 802.3 and 802.11 are better known and what is the key defining physical factor that distinguishes between the two? 2 marks (d) IEEE 802.3 and 803.11 both adopt a MAC protocol underpinned by a mechanism described by the acronym CSMA. Define what is meant by this acronym and explain, briefly, the fundamental differences between the 802.3 and 802.11 implementations. Discuss why such a difference in implementation is necessary. IEEE 802.11 standards offer potentially high (Mbit/s) transmission rates. Explain briefly why the actual throughput experienced by any individual station can fall significantly short of the "headline" rates. Other than their CSMA implementation, state TWO other significant differences between IEEE 802.3 and 802.11 MACs. 8 marks (e) Explain, briefly, how 802.11 networks deal with the variable characteristics of its physical transmission channel and why such mechanisms are not applied in 802.3 networks. 2 marks
