Resolution

This term is used to describe how fine of an image a monitor can display and a printer can print. With printers, resolution is measured by the number of pixels per inch the printer can print. This measurement is known as dots per inch, or "dpi". Similarly, the resolution of a scanner is measured in dpi. 600 dpi is a reasonable resolution for a consumer level printer or scanner. Because the sizes of monitors differ, monitor resolution can't be measured in dpi. Instead, the resolution of a monitor refers to the number of pixels that can be displayed on the screen. For example, in a 640 x 480 resolution, there are 640 horizontal lines are drawn across the screen and 480 drawn vertically. Some common monitor resolutions are 640 x 480, 800 x 600, 1,024 x 768, and 1,280 x 1,024.
