How is a wireless access point that is also a bridge more efficient in handling network traffic than a wireless access point that is not a bridge?
The AP helps to reduce the overall volume of network traffic by not allowing data frames across the bridge if it knows that the frame is addressed to a destination on its own segment.

Describe the difference between a hub and a switch.
A hub transmits data to every device connected to it, without regard for what kind of data is passing through and where the data might be going.
A switch keeps track of devices (by their MAC address, after learning it) it is connected to, so it is a smarter hub.
