Words worth knowing

Start with the plain-language meaning, then reach for the technical definition when you need precision.

Baud rate

Also: symbol rate

Link to term
In plain language

The number of transmitted symbols per second.

Technical definition

Baud equals bit rate only when each symbol carries one bit; asynchronous UART peers also need matching framing and tolerable clock error.

Units
baud (symbols/s)

Example A binary UART configured at 115200 baud nominally sends 115200 symbols/s.

Common misconception Baud is not universally identical to bits per second.
