What is Bit?

A bit (binary digit) is the smallest unit of digital information. Eight bits equals one byte. Digital images are often described by the number of bits used to represent each pixel, i.e., a 1-bit image is monochrome; an 8-bit image supports 256 colors or grayscales; while 24 or 32-bit images support an even greater range of color.
