Explanation:
Detailed explanation-1: -The waiting time that a station waits before attempting retransmission of the frame is called as back off time.
Detailed explanation-2: -The back off timer significantly reduces the number of collisions and corresponding retransmissions, especially when the number of active users increases.
Detailed explanation-3: -Back Off Algorithm is an algorithm used for collision resolution. It works as, When this collision occurs, both the devices wait for a random amount of time before retransmitting the signal again, they keep on trying until the data is transferred successfully.
