We consider a link connecting two hosts. The link has a bit rate of 100 Mbps and covers a distance of 200 m. Assume that the propagation velocity of the signal is 2*10⁸ m/s.

a) What is the minimum packet size, so that both hosts detect all collisions? (8 points)

b) Suppose that we want to use a link with 10 Gbps bit rate, what is the new minimum packet size? (8 points)

c) Based on the results, state a possible disadvantage of using links with high bitrate in local area networks. (4 points)
