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.bhphotovideo
From binary digit, is a basic unit of data storage, and has a value of either 0 or 1.Eight bits = one byte (See Byte below)
Determines the maximum number of colors that can be displayed at one time. Bit depth is the number of bits per pixel, which determines the number of colors that the image can display. The minimum requirement for a color photograph is eight bits per pixel.
