Baud rate and Bits per second are essentially the same thing. For example, if you have a 2400 baud modem, you can transfer 2400 bits per second. Bytes per second is another story, however. Data sent over the modems is broken down as follows: +-----------+-----------+-------------+ | START BIT | DATA BITS | STOP BIT(S) | +-----------+-----------+-------------+ where START BIT is 1 bit, DATA BITS is generally 8 bits (without parity), and STOP BITS is usually 1 bit. These numbers can vary, but this is the most common format used today. What this means is that for each BYTE of data you send, you actually send 10 bits, not just 8. So your effective BYTES PER SECOND would be 240 for a 2400 baud modem. Most of the newer modems also use compression techniques to help improve the EFFECTIVE baud rate.
