Knowing the various components within a network is a fundamental skill for any network engineer qualified to work at Cisco. The best way to respond to this type of question is to provide a general description of the devices and then discuss each device's unique features and functions. You should also compare and contrast them, noting their benefits.

"A hub, switch, and router are network devices used to move data around the network. They are all a type of switch, but with different features and functions. The hub is the least expensive, intelligent, and complicated of the three. It broadcasts all data to every node but may cause serious security and reliability issues. A switch works similar to hubs but more efficiently. It creates dynamic connections, only communicating to designated nodes. The router is the smartest and most complicated out of these three devices. It is like a little computer dedicated for routing network traffic to specific nodes or devices."
