reasonable compromise. Describe the problems that can occur if the timeout
value is too small or too large.
c) IEEE defines two sublayers at Layer 2, discuss the purpose of each.
d) How does a computer attached to a shared LAN decide whether to accept a
packet?
e) Expand the acronym CSMA/CD, explaining each part and why CSMA/CD uses a
random delay?
f) Explain why cllision is an issue in a random-access protocol but not in
reservation or channel partitioning protocols.
