When a collision occurs, IEEE 802.3 systems use an algorithm called binary exponential back off to calculate the random amount of time the sender must wait before at-tempting to retransmit the frame. For each of the retransmissions, the algorithm doubles the range of the random delay. After n collisions, the system will wait for a random amount of time, in the range from 0 to 2^n -1 units of time before attempting to retransmit the frame. Analyze the advantages of this design decision.
