2. Definition:
computer graphics is the technology that deals
with designs and pictures on computers.
An example of computer graphics is the design
of pictures and scenes on a computer game.

5. Graphics hardware output devices are
those hardware that generates computer
graphics and allows them to be shown on a
display..

6. Output
Devices
Plotters
Monitors
Phosphors
Electron
Gun
Printers

7. This allows you to print off the graphics you
create and edit on the computer. You can print
them off in color, black and white or gray scale in
various sizes.

8. Plotter is another type of computer printer
which prints vector graphics. There are two
types of plotters one is a pen plotter which is
when a pen moves across the surface of the
paper and then there is a knife plotter which
uses moving knives to cut into a piece material.

9. This allows you to see the images produced by
the computer.
The quality of the graphics that you see
depends on the size and the resolution of the
monitor.

10. The phosphors used in a graphic display are
normally chosen for their color characteristics and
persistence. Color should preferably white,
particularly for applicants where dark information
appears on a light background.
Phosphor layers provide most of the light produced
by fluorescent lamps, and are also used to improve
the balance of light produced by metal halide lamps.

11. Electron Gun makes use of electrostatic fields
to focus and accelerate the electron beam. A
field is generated when two surfaces are raised
to different potentials.
The most common use of electron guns is in
cathode ray tubes, which were widely used in
computer and television monitors.
