Question

Which of the following is true about the CSMA/CD algorithm?

The algorithm never allows collisions to occur.

Collisions can happen, but the algorithm defnies how the computers should notice a collision and how to recover.

None of the other answers is correct.

The algorithm works with only two devices on the same Ethernet.

None of the other answers is correct.

The algorithm works with only two devices on the same Ethernet.

Explanation / Answer

A) This statement is false as in the CSMA/CD algorithms, collisions occur.

B) This statement is true.

CSMA/CD is a Media Access Control(MAC) method. The algorithm uses a carrier -sensing scheme. In this scheme, a transmitting station detects collision by sensing transmission from other stations while transmitting a frame. Whenever a collision condition is detected, the concerned station stops transmitting frames, and instead transmits a jam signal, and waits for a random time interval before trying to resend the frames.

C) Clearly this statement is also false.

D) CSMA/CD is MAC method used for local area networking in early Ethernet technology. So it is possible that there are more than two devices present on the same ethernet. Hence, this statement is also false.
