memory. A bit can have the value 0 or 1, which represents the OFF and

Bit map

 

An image representation in which each point in the image is separately

 

defined. For monochrome images, each point is defined by a single unit

 

of information. For color images, each point is defined by several units of

 

information, representing the different color elements.

 

The characters produced by a dot matrix printer are a kind of bit map.

 

Each character image is created by defining the points in the dot matrix as

 

either on or off.
