resolution

Definition:

A term used to describe the number of dots (or pixels) used to display an image. The higher the resolution, the better the quality of the picture. The resolution of a computer monitor is indicated by number combinations like 800 x 600. This means that there are 800 dots horizontally across the monitor and 600 dots vertically. In this example, 480,000 dots would make up the image you see on your monitor.
