CSMA Protocol Quiz

What does CSMA stand for?

• Carrier Sense Multiple Access

• Channel Signal Multiple Access

• Carrier Signal Multiple Access

• Channel Sense Multiple Access

What is the main principle of CSMA?

• Sense before transmit

• Sensing is optional

• Transmit before sensing

• Transmit continuously

Which of the following is NOT a type of CSMA?

• One Persistent CSMA

• Non-Persistent CSMA

• Two Persistent CSMA

• P-Persistent CSMA

What happens when two stations transmit data simultaneously on a shared medium?

• Data is queued

• Data is transmitted successfully

• Data is ignored

• Collision occurs

In One Persistent CSMA, what does a station do when the channel is busy?

• Transmit immediately

• Wait indefinitely

• Randomly check the channel

• Continuously sense the channel

What is the behavior of Non-Persistent CSMA when the channel is busy?

• It ignores the channel

• It transmits immediately

• It continuously senses the channel

• It waits for a random period of time

What does P-Persistent CSMA apply to?

• Wireless channels

• Slotted channels

• Dedicated channels

• Unslotted channels

What is a key characteristic of P-Persistent CSMA?

• Always transmits immediately

• Does not sense the channel

• Transmits with probability P

• Waits for a fixed time

What is the effect of propagation delay in CSMA protocols?

• It has no effect

• It increases collision chances

• It improves performance

• It reduces collision chances

What is the main advantage of Non-Persistent CSMA over One Persistent CSMA?

• Better channel utilization

• Higher throughput

• Faster transmission

• Lower delays
