Actives nodes, adapter, ethernet
a. What is the probability that node A succeeds for the first time in slot 5?
b. What is the probability that some node (either A, B, C or D) succeeds in slot 4?
c. What is the probability that the first success occurs in slot 3?
d. What is the efficiency of this four-node system?
2. Recall that with the CSMA/CD protocol, the adapter waits K.512 bit times after a collision, where K is drawn randomly. For K = 100, how long does the adapter wait until returning to Step 2 for a 10Mbps Ethernet? For a 100 Mbps Ethernet?
