Baud

: In simple binary systems (like standard UART), one symbol equals one bit, so

While often used interchangeably in simple serial communication, they are technically distinct: : The number of symbols per second. Bit Rate (bps) : The number of bits per second. : In simple binary systems (like standard UART),

: Lower baud rates (e.g., 9600) are more reliable over longer cables or in noisy environments. one symbol equals one bit
