What is the Resolution
Refers to the sharpness and clarity of an image. The term is most often used to describe monitors
, and bit-mapped
graphic images. In the case of dot-matrix
and laser printers
, the resolution indicates the number of dots per inch
. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots
in a line 1 inch long. This means it can print 90,000 dots per square inch.
For graphics monitors
, the screen resolution
signifies the number of dots (pixels
) on the entire screen
For example, a 640-by-480 pixel screen is capable of displaying 640
distinct dots on each of 480 lines, or about 300,000 pixels. This
translates into different dpi measurements depending on the size of the
screen. For example, a 15-inch VGA
monitor (640x480) displays about 50 dots per inch.
Printers, monitors, scanners
, and other I/O devices are often classified as high resolution, medium resolution,
or low resolution
. The actual resolution ranges for each of these grades is constantly shifting as the technology improves.
