per second. When one bit is the standard "event," this is a measure of
bits per second (bps). For example, a baud rate of 50 means
transmission of 50 bits of data per second.
Binary digit. One bit is the basic unit of binary information. Generally,
eight consecutive bits compose one byte of data. The pattern of 0 and
1 values within the byte determines its meaning.
