Final answer:
A switch is the best choice for interconnecting networking devices due to its ability to direct data to specific devices, thereby reducing unnecessary network traffic and increasing security.
Step-by-step explanation:
When choosing between a hub and a switch for interconnecting networking devices, a switch is generally considered the best choice. A hub simply forwards the data it receives to all other ports, which can result in a lot of unnecessary traffic and can lead to security concerns because all devices connected to the hub can see all the traffic. On the other hand, a switch is more intelligent and can direct data to the specific device that needs it, reducing network traffic and increasing security.
