that can be used to decorate a document.

4. pros
•Images are always available as they are
always there.

needed in a network e.g. cabling.

6. pros
•Symbols can be
recognized throughout the
world.
cons
•Hard to keep up to date
•New components are not
always available
immediately

7. Vector graphics:
Graphics saved as geometric equations
Bitmap graphics:
Graphics saved as pixels

8. Produced when a scanner or camera is used. Clip art are saved as bitmap
images. This means that clip arts can be changed or edited according to the
need of the user. Bitmap images can be saved as JPEG or GIF files.
