It categorizes computer devices into input, processing, output, and storage devices, explaining their roles in a computer system. The information emphasizes how these components work together to process data and produce results.

1. Functions of
Computer
System

2. Computer Peripherals and Devices
Computer peripherals are other parts connected to the computer.

3. BASIC PARTS OF A COMPUTER
MONITOR - The monitor allows you to see what you and
your computer are doing together. It looks like a TV screen.

4. BASIC PARTS OF A COMPUTER
SYSTEM UNIT - It is the brain and heart of computer. The system unit is the

the letters or numbers on the keyboard.

6. Computer Peripherals and Devices
A mouse is a handheld pointing device used to position a cursor on a computer screen. This
allows the user to select items stored on a computer.

7. Computer Peripherals and Devices
The scanner copies a picture or document into the computer.

8. Computer Peripherals and Devices
The microphone allows you to record your voice and other sounds.

9. Computer Peripherals and Devices
The joystick is used in playing computer games. It works like the mouse
and the arrow keys found in the keyboard.

10. Computer Peripherals and Devices
The digital camera or digicam captures pictures into a computer. These
pictures or images can be saved in the computer.

11. Computer Peripherals and Devices
The printer takes what you see on the computer screen and prints it on
paper. The printed copy is called hard copy. It can be in color or in black.

12. Computer Peripherals and Devices
The speaker produce sounds coming from the computer. They add
excitement to playing computer games. They also allow you to hear your
favorite music.

13. Computer Peripherals and Devices
The headphone is a handy speaker placed directly over the ears. It allows
the user to listen to the sound coming from the computer.

14. COMPUTER DEVICES
1. Input devices
2. Processing devices
3. Output devices
4. Storage devices

15. COMPUTER DEVICES
They are parts of a computer that receive instructions from the user. They also give commands
to the computer.
Input devices
Examples of Input devices

16. COMPUTER DEVICES
This device is a part of a computer that
processes the instructions received from the
input devices. The system unit is the case
that contains all the electronic components
of any computer system. The electronic
components are considered internal
hardware seeing that they are inside the
system unit and you cannot see when you
look at the computer. These components
inside the system unit are what process the
data and really makes the computer work.
Processing devices

17. COMPUTER DEVICES
They are parts of a computer that produces the results of the instructions processes by the
Central Processing Unit.
Output devices
Examples of Output devices

18. COMPUTER DEVICES
They are devices that store data or information. Some storage devices are permanently
installed in the computer, others are portable and may be transported.
Storage devices / Media
Examples of Storage devices/Media
HARD DISK DRIVE COMPACT DISC
FLOPPY DISC PEN DRIVE
