Suppose nodes A and B are on the same 10 Mbps broadcast channel and the propagation delay between the two nodes is 254 bit times. Consider the situation where A and B send ethernet frames at the same time and they collide anf the A selects K=0 and B selects K-1 in the CMSA/CD retry mechanism. Assume these 2 are the only active nodes in the channel show that retransmission from A to B does not collide.
