. ___________ is a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously and encounter a data collision.

(A) CSMA/CD
(B) CSMA/CA
(C) TCP/IP
(D) TCP/UDP

Answer: A - CSMA/CD address is the correct answer. CSMA/CD is a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously and encounter a data collision. The rules define how long the device should wait if a collision occurs. If no transmission is taking place at the time, the particular station can transmit but If two stations attempt to transmit simultaneously, this causes a data collision, which is detected by all participating stations. After a random time interval, the stations that collided attempt to transmit again.
