2.3 Output devices and their uses
Cathode Ray Tube (CRT) Monitor
Use: As primary output display for computers.
Chapter 2: Input and output devices
Advantage: Cheaper than other monitors and can be used with light pens.
Resolution is also very good.
Disadvantage: Size is bigger – requires more desk space.
Could be a safety hazard if not correctly supported.
Liquid Crystal Display (LCD) Monitor
Use: Have taken over from CRT as primary output display for computers. Also
primary output for monitors.
Flat Screen
Advantage: Smaller and lighter so less desk space required.
Consumes less power and does not generate as much heat as CRT monitors.
Disadvantage: Resolution may not be as good as a CRT monitor.
