baud
A unit of speed that measures the rate at which
information is transferred. Baud rate is the reciprocal of
the length in seconds of the shortest pulse used to carry
data. For example, a system in which the shortest pulse
is 1/1200 second operates at 1200 baud. On RS-232
serial lines, the baud rate equals the data flow rate in bits
per second (bps). To communicate properly, a printer
must be configured to operate at the same baud rate as
its host computer.
