BAUD- Just Say NO!


Okay, everyone needs a pet peeve. Mine (which I must admit was inherited from Ron Hoffmann and Dennis Baron) is the mis-use of the word baud. Where is it mis-used? Just about everywhere.
BAUD: A unit of signaling speed equal to the number of discrete conditions or signal events per second. In asynchronous transmission, the unit of signaling speed corresponding to one unit interval per second; that is, if the duration of the unit interval is 20 milliseconds, the siganling speed is 50 baud. Baud is the same as "bits per second" only if each signal event represents exactly one bit. A baud is the reciprocal of the unit interval.

Technical Aspects of Data Communication, John E. McNamara


An specific example are modems. A 9600bps modem is really 2400 baud, because each event represents 4 bits. As far as modems go, if the speed is over 600bps, bps != baud.
