Devices on one network can communicate with devices on another network via a-
A and B are two stations on a Ethernet. Each has a steady queue of frames to send. Both A and B attempts to retransmit after a frame collide and A wins the first back off race. At the end of this successful transmission by A, both A and B attempt to transmit and collide. The probability that A wins the second back off race is
