Which of the following is true about the CSMA/CD algorithm?Question 5Select one:The algorithm never allows collisions to occur.The algorithm works with only two devices on the same Ethernet.None of the other answers are correct.Collisions can happen, but the algorithm defines how the computers should notice a collision and how to recover.

The correct answer is: Collisions can happen, but the algorithm defines how the computers should notice a collision and how to recover.

Here's why:

CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. It's a network protocol for carrier transmission used in Ethernet networks.

1. The statement "The algorithm never allows collisions to occur" is incorrect. In fact, the whole point of CSMA/CD is to handle situations when collisions do occur.

2. The statement "The algorithm works with only two devices on the same Ethernet" is also incorrect. CSMA/CD is designed to manage multiple devices on the same network.

3. The statement "None of the other answers are correct" is incorrect because the last statement is correct.

4. The statement "Collisions can happen, but the algorithm defines how the computers should notice a collision and how to recover" is correct. CSMA/CD allows devices to attempt to access the network whenever they want. If a device detects that another device is transmitting, it will wait and try again later. If two devices transmit at the same time and a collision occurs, they detect this, stop transmitting, and each waits a random amount of time before attempting to transmit again.
