Computer Hardware Terms, Glossary and Dictionary

Monochrome basically means one color. In computing, monochrome has two meanings: it can mean having only one colour which is either on or off, or also allowing shades of that colour, although the latter is more correctly known as greyscale. Monitors, for example, can be monochrome, grayscale or color. Monochrome monitors actually use two colors, one for the display image (the foreground) and one for the background. Graphic images can also be monochrome, grayscale, or color.
