Which of the following devices extends the network and has the capacity to store frames and act as a storage
and forward device?

A.
Router

B.
Bridge

C.
Repeater

D.
Gateway

Explanation:
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.
Incorrect answers:
A:
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.
C:
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.
D:
Gateways provide access paths to foreign networks.
