baud

( /bawd/, n.)

   [simplified  from  its  technical  meaning] n. Bits per second. Hence
   kilobaud  or  Kbaud,  thousands  of  bits  per  second. The technical
   meaning is level transitions per second; this coincides with bps only
   for  two-level  modulation with no framing or stop bits. Most hackers
   are aware of these nuances but blithely ignore them.

   Historical  note:  baud was originally a unit of telegraph signalling
   speed,  set at one pulse per second. It was proposed at the November,
   1926   conference   of   the  Comité  Consultatif  International  Des
   Communications  Télégraphiques as an improvement on the then standard
   practice  of  referring  to line speeds in terms of words per minute,
   and  named  for  Jean  Maurice  Emile  Baudot  (1845-1903),  a French
   engineer who did a lot of pioneering work in early teleprinters.
