In engineering, a unit of electrical signaling speed equal to one pulse per second, measuring the rate at which signals are sent between electronic devices; such as, telegraphs and computers.

For example, 300 baud (or bauds) is about 300 words a minute or a unit of speed in data transmission of a computer equal to one bit per second; or, a unit of transmission speed for electronic signals, corresponding to one information unit or event per second.

Named after Jean Maurice Emile Baudot (1845-1903), a French engineer.
