2-7-94 Baud vs BPS
Using BAUD to refer to Bits Per Second modem speed is wrong (though
common practice). NEVER use the word BAUD when talking to a customer.
ALWAYS use BPS or Bits Per Second. Don't unecessarily correct the customer,
but do not make the mistake because 'he' does.
BAUD refers to the number of 'wave modulations' per second sent over
the phone line. 300 Baud and 300 BPS are the same, because each modulation
carried 1 BIT. There were a few 600 Baud modems with 1 bit per baud made.
But about then someone invented encoding, so each Baud could carry more
than 1 Bit. At first it was 2 bits at 600 baud which gave 1200 BPS. Then
they improved the encoding to give 4 bits per baud to make 2400 BPS modems.
When they increased the Baud to 2400, the encoding stayed the same, 4 bits
per baud, giving us V32 modems at 9600 BPS.
Now we have even better encoding for 14,400 (6 bits) and completely
different encoding to give the V-fast modems. But remember, that BAUD does
NOT equal BPS.
