Answer: A
A gateway performs the job of translating e-mail formats
from one network to another so messages can make their way
through all the networks. A protocol converter is a hardware
device that converts between two different types of
transmissions, such as asynchronous and synchronous
transmissions. A front-end communication processor connects
all network communication lines to a central computer to
relieve the central computer from performing network
control, format conversion and message handling tasks. A
concentrator/multiplexor is a device used for combining
several lower-speed channels into a higher-speed channel.
