8. HOW DO COMPUTERS WORK?
• Input--This is when information is entered into a
computer. Some common input devices include
the keyboard, mouse and scanner.
• Output--This is the information that comes out of
a computer after it has been processed. The
information comes out on output devices such as a
printer or computer monitor.
• Processing--This is when the information is
handled by the computer’s brain, known as the
CPU (Central Processing Unit).
9. PARTS OF COMPUTER SYSTEM
Hardware
The hardware is the part of the computer
you can touch and see.
Mechanical devices in the computer
Software
Software is a part of the computer you
cannot touch.
Software consist of computer programs and
procedures that perform some tasks on your
1B-9 computer.
10. INPUT DEVICES
• The Mouse is the small
hand held device that
attaches to the
computer. It may have
two or three buttons. The
mouse is used to move
the cursor on the screen.
