Your network has 20 computers connected to a hub You want to

Your network has 20 computers connected to a hub. You want to increase performance by reducing the size of the collision domain as much as possible. Which of the following devices can be used to do this?

A. A hub

B. A bridge

C. A switch

D. None of the above

Solution

C: A switch: it can be a valuable asset to networking. Overall, they can increase the capacity and speed of your network.Switches occupy the same place in the network as hubs. Unlike hubs, switches examine each packet and process it accordingly rather than simply repeating the signal to all ports.As more users are added to a shared network or as applications requiring more data are added, performance deteriorates. This is because all users on a shared network are competitors for the Ethernet bus. A moderately loaded 10 Mbps Ethernet network is able to sustain utilization of 35 percent and throughput in the neighborhood of 2.5 Mbps after accounting for packet overhead, inter-packet gaps and collisions.
