baud

baud (bôd, bōd), measure of the rate at which signals are transmitted over a telecommunications link. It is equivalent to the number of elements or pulses transmitted in one second, e.g., in computer input/output, 2400 baud equals 2400 bits per second (bps) if each pulse encodes one bit (either 0 or 1). Many modems permit the encoding of several bits per baud. A 9600-bps modem that operates at 2400 baud sends four bits per baud by using a range of 16 tones (representing the four-bit combinations 0000 to 1111) to transmit data, and data compression can boost the effective transmission rate even higher. Because of this, the data transfer rate of a modem is measured in bits per second.

baud

baud / bôd/ • n. (pl. same or bauds) chiefly Comput. a unit used to express the speed of transmission of electronic signals, corresponding to one information unit or event per second. ∎  a unit of data transmission speed for a modem of one bit per second (in fact there is usually more than one bit per event).

baud

baud Unit for measuring the speed at which a digital communications device carries information. One baud is equal to one bit per second. Although the term baud rate is still widely used, the speed of modern equipment is often expressed in kilobits per second (kbps). See also modem
