Bit is an abbreviation for Binary Digit. It is the smallest unit of information a computer can read. A single bit can hold only one of two values: 0 or 1, More meaningful information is obtained by combining consecutive bits into larger units. For example, a byte is composed of eight consecutive bits. Graphics are also often described by the number of bits used to represent each dot on a display. A one bit image can be either pure black or white; an eight-bit image supports 256 colors or greyscales; and a 24-bit or 32-bit graphic supports True Color, which is 16.7 million colors. Bit depth refers to the number of bits used to represent the color of each dot, or pixel on a display screen.
