What are two characteristics of the CSMA/CD access method? (Choose two.)

Question

Options

• AIt checks to see if a collision has been detected.
• BIt does a round robin search for requests to transmit from all nodes on the network.
• CIt signals its intent to transmit on the network.
• DIt waits until the transmission medium is idle.

• A
  73% (29)
• B
  8% (3)
• C
  20% (8)

Explanation

Main procedure for the CSMA/CD: 1. Is my frame ready for transmission? If yes, it goes on to the next point. 2. Is medium idle? If not, wait until it becomes ready 3. Start transmitting. 4. Did a collision occur? If so, go to collision detected procedure. 5. Reset retransmission counters and end frame transmission. Carrier Sense Multiple Access With Collision Detection (CSMA/CD) is a media access control method used most notably in local area networking using early Ethernet technology. It uses a carrier sensing scheme in which a transmitting data station detects other signals while transmitting a frame, and stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame.
