Question

In a bridged network, two bus segments are interconnected via a bridge. There are two hosts  attached to each of the segments (Host A, B, C, D).

  • How many collision domains does the network have? How many broadcast domains does the network have? 
  • If two hosts on one segment (Hosts A & B) transmit intra-segment frames at the same time, what role does CSMA/CD play to ensure that the two hosts will finally achieve successful transmissions? Explain !. 
  • If one host on one segment (Host D) transmits an inter-segment frame (to Host B) and a host on the destination segment (Host A) begins to transmit an intra-segment frame just as the first frame is approaching the bridge. Explain whether or not there will be successful transmissions. What role does the CSMA/CD play in this scenario (if at all).
