Having seen what the various storage devices are, let's now have a look at the display devices.
Display device is the visual output device of a computer, commonly called a monitor.
- A monitor looks like a television.
- The monitor will display what the user is doing, so he or she can see it before producing a hard copy.
- The resolution or clarity of the image on the monitor depends on the number of individual dots displayed on the screen and the distance between them.
- Each dot is a picture element (or pixel) and the distance between them is the dot pitch. The more advanced the graphics the user will be using, the better resolution required.
- Two popular kinds of viewing screens are cathode ray tubes and flat-panel displays.
- A color monitor can display text or graphics in color.
