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

a: All stations stop transmitting and wait for a random backoff time Explanation

Explanation

b: The station that detected the collision continues transmitting Explanation

Explanation

c: The station that detected the collision stops and resends immediately Explanation

Explanation

d: All stations stop transmitting permanently Explanation

Explanation

How does the backoff algorithm in CSMA/CD help in collision resolution?

a: It allows all stations to retransmit at the same time Explanation

Explanation

b: It ensures stations wait a fixed time before retransmitting Explanation

Explanation

c: It introduces a random delay before retransmission to reduce further collisions Explanation

Explanation

d: It prioritizes some stations over others to avoid collisions Explanation

Explanation

Why does CSMA/CD use a backoff algorithm after a collision?

a: To increase network speed Explanation

Explanation

b: To ensure devices transmit again at the same time Explanation

Explanation

c: To introduce a random delay and reduce repeated collisions Explanation

Explanation

d: To prioritize certain devices over others Explanation

Explanation

What determines the minimum packet size in Ethernet?

a: The processing speed of the switches Explanation

Explanation

b: The propagation delay and collision detection requirements Explanation

Explanation

c: The total number of devices on the network Explanation

Explanation

d: The number of packets sent per second Explanation

Explanation

Which of the following best describes binary exponential backoff?

a: A method to increase network bandwidth Explanation

Explanation

b: A way to ensure no device transmits data at the same time Explanation

Explanation

c: An algorithm that increases wait time exponentially after each collision Explanation

Explanation

d: A technique to detect hidden terminals in wireless networks Explanation
