The baud rate is a measure of the number
of symbols (characters) transmitted per unit of time. Each symbol
will normally consist of a number of bits, so the
baud rate will only be the same as the
bit rate when there is one bit per symbol. The
term originated as a measure for the transmission of telegraph
characters. It has little application today except in terms of
modem operation. It is recommended that all data rates are
referred to in bps, rather than baud (which is easy
to misunderstand). Additionally, baud rate cannot be equated to
bandwidth unless the number of bits per symbol is known.
