Definition: The smallest unit of information usable by a computer.
Definition: The basic unit in a binary numbering system. Binary Digit. A single bit is expressed in the base 2, either on or off. Imagine using bits of data to express gray scale. Progressive levels display are expressed as increasing powers of 2. In a one bit system (21) there would only be white or black. A four bit system is 24 (16 gray scale levels) where a six bit system is 26 (64 levels of gray). The more gray, the better the picture. Bit depth This refers to the grey scale range of an individual pixel. A pixel with 8 bits per colour gives a 24 bit image (8 bits X 3 colours is 24 bits). CCD sensors are coloured in a pixel by pixel method. 30/32 bit colour is billions of colours 24 bit colour resolution is 16. 7 million colours. 16 bit colour is 65,536 colours 8 bit colour is 256 colours 8 bit grey scale is 256 shades of grey 1 bit is black or white.
