Baud Rate or Baud
The data transfer rate between two devices, such as your computer and 
your printer. Both devices must be configured for the same baud rate.  Your 
printer’s baud rate ranges from 300 to 38,400 bits per second.
Bit
An acronym for binary digit. The bit is the most fundamental unit of 
information that a computer can accept. It has two states called 1 (one) and 
0 (zero), or on and off, and can be used to represent a yes/no statement. 
Groups of bits are used to represent more complex statements, such as 
characters. The most common grouping of bits is called a byte, which 
consists of 8 bits. See also

Buffer
Storage space used to compensate for a difference in rate or sequence of 
data flow when transmitting data from one device to another.
