How does CSMA/CD detect a collision?

a: By waiting for an acknowledgment signal Explanation

Explanation

b: By continuously monitoring the transmission medium Explanation

Explanation

c: By using a token-based system Explanation

Explanation

d: By sending a preemptive jam signal Explanation

Explanation

Why is CSMA/CD not commonly used in modern Ethernet networks?

a: Because wireless networks are more efficient Explanation

Explanation

b: Because modern Ethernet uses full-duplex communication Explanation

Explanation

c: Because CSMA/CD is not effective at high speeds Explanation

Explanation

d: Because token-ring networks have replaced Ethernet Explanation

Explanation

What does the 'Carrier Sense' in CSMA/CD refer to?

a: A device continuously transmits data without checking the medium Explanation

Explanation

b: A device listens to the network before transmitting data Explanation

Explanation

c: A device sends a jam signal after every transmission Explanation

Explanation

d: A device only transmits when another device is already sending Explanation

Explanation

What happens when a collision is detected in CSMA/CD?

a: The devices continue transmitting the data Explanation

Explanation

b: The network switches to half-duplex mode Explanation

Explanation

c: A jam signal is sent, and transmission is stopped Explanation

Explanation

d: The collision is ignored, and data transfer resumes Explanation

Explanation

How does CSMA/CD handle multiple collisions?

a: By using a fixed backoff time for all devices Explanation

Explanation

b: By increasing the backoff time exponentially after each collision Explanation

Explanation

c: By allowing all devices to transmit simultaneously Explanation

Explanation

d: By ignoring the collisions and continuing transmission Explanation
