Baud
Last updated
A unit measuring the rate of signal changes per second in data transmission, used especially in telecommunications and early computer modems.
See it in a sentence
Early dial-up modems transmitted data at a mere 300 baud.
Engineers distinguish baud rate from bit rate, since each signal change can encode more than one bit.
A note on using this word
The unit is named after Emile Baudot, a French engineer who developed an early telegraph code, though "baud" is often mistakenly used interchangeably with "bits per second."
