substance in a given volume (expressed as moles/cubic

meter)

2: the spatial property of being crowded together [syn: {density},

{denseness}, {compactness}] [ant: {distribution}]

3: strengthening the concentration (as of a solute in a

concentrator

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}

device.

For example, a concentrator may be used to connect 24 2400 bps

TTYs to a host via a 57600 bps channel.
