Written Lab 2.2: CSMA/CD Operations

Question 1

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) helps to minimize collisions in the network, thereby increasing data transmission efficiency. Place the following steps of its operation in the order in which they occur after a collision.

• All hosts have equal priority to transmit after the timers have expired.
• Each device on the Ethernet segment stops transmitting for a short time until the timers expire.
• The collision invokes a random backoff algorithm.
• A jam signal informs all devices that a collision occurred.

Answer 1

1. A jam signal informs all devices that a collision occurred.
2. The collision invokes a random backoff algorithm.
3. Each device on the Ethernet segment stops transmitting for a short time until the timers expire.
4. All hosts have equal priority to transmit after the timers have expired.
