Output is processed data or information

It typically takes the form of text, graphics, photos, audio, or video

Output devices are any hardware used to provide or create output from the computer, e.g. printers, monitors, speakers, etc.

About   resolution, dot pitch, refresh rate, and size.

§          Clarity: the quality and sharpness of a monitor; depends on:

§          Resolution: measured in Pixels (Picture Elements) e.g. a 1,280 x 1,024 resolution screen displays 1,310,720 pixels.  The greater the number of pixels, the better the resolution.

§          Dot Pitch: the distance between pixels, typically measured in millimeters.  Most monitors have a dot pitch less than 0.3 mm.  The smaller the dot pitch, the better the clarity.

§          Refresh Rate: how often the image is “re-drawn” on the monitor.  Most monitors have a refresh rate of 75 Hz or better (image refreshes 75 times every second).  The faster the rate, the better the image

§          Size or Viewable Size: the diagonal length of the monitor’s viewing area.  Smaller monitors have better image quality, but it’s also smaller to view
