Answer: B

A bridge connects two separate networks to form a logical
network (e.g., joining an ethernet and token network) and
has the storage capacity to store frames and act as a
storage and forward device. Bridges operate at the OSI data
link layer by examining the media access control header of a
data packet. Routers are switching devices that operate at
the OSI network layer by examining network addresses (i.e.,
routing information encoded in an IP packet). The router, by
examining the IP address, can make intelligent decisions in
directing the packet to its destination. Repeaters amplify
transmission signals to reach remote devices by taking a
signal from a LAN, reconditioning and retiming it, and
sending it to another. This functionality is hardware
encoded and occurs at the OSI physical layer. Gateways
provide access paths to foreign networks.
