Quizplus · Accepted Answer

The term “fight” indicates a sense of competition, which is exactly the characteristic of the contention method. In this method, each device tries to access the shared medium at any time and transmits data if the medium is free. If two devices try to transmit simultaneously, a collision occurs, and the data gets lost.
