The definition of bitA bit can either be on or off; one or zero. All computer
data can ultimately be reduced to a series of bits. The
term is also used as a (very rough) measure of sound
quality, color quality, and even
procesor capability by
considering the fact that series of bits can represent binary numbers.
For example (without getting too technical), an eight bit
image can contain at most 256 distinct colors while a
sixteen bit image can contain at most 65,536 distinct
colors.
