If three devices are plugged into one port on a switch and two devices are plugged into a different port, how many collision domains are on the switch?
Click on the arrows to vote for the correct answerA. B. C. D.
The concept of collision domain comes from the Ethernet networking technology, where a collision domain refers to a segment of a network where packets can collide with each other due to sharing the same physical medium. In a switched network, each port on the switch represents a separate collision domain.
In the given scenario, three devices are plugged into one port on a switch, and two devices are plugged into a different port. To determine the number of collision domains on the switch, we need to count the number of ports that have devices connected to them.
Therefore, the switch has a total of two collision domains, one for each port with connected devices.
Hence, the correct answer is A. 2.
