The Free On-line Dictionary of Computing (foldoc)

A device that combines the data streams from
many simultaneously active inputs into one shared channel in
such a way that the streams can be separated after
transmission. The concentrator's output bandwidth must be at
least as great as the total bandwidth of all simultaneously
active inputs. A concentrator is one kind of {multiplexing}
