The document discusses the main components of a computer hardware system. It describes the system unit, monitor, mouse, keyboard, scanner, printer, and speakers. The system unit contains the motherboard, CPU, RAM, ROM, slots, and CMOS battery. The monitor displays information for the user to see. The mouse is a pointing device, while the keyboard allows users to type. Additional devices like the scanner and printer allow input and output between hard copy and soft copy formats. Speakers output sound.

2. Objective
• The main objective is to learn
about the different components
that make a computer work. It is
also a must to learn the functions
of each part of the computer and
how they work.

3. Outline
• What is a computer?
• Different parts that make up a computer
• System unit and it’s internal components
• Monitor and it’s function
• Mouse, the smallest component
• Keyboard, the typing device
• Scanner, from hard to soft copy
• Printer, from soft to had copy
• Speaker, output sound

4. What is a computer?
A computer is a technical machine
made up of many different
physical components that are
called computer hardware.

5. Different components of the
computer
• System unit
• Monitor
• Mouse
• Keyboard
• Scanner
• Printer
• Speaker

6. System unit and it’s
internal components
• System unit is actually the box which contains
many different small components of a computer
• Motherboard
»CPU
»RAM
»ROM
»SLOTS
»CMOS Battery

7. Monitor and it’s function
• A monitor is a device which shows and
displays data or information on the
computer.
• The function is to enable the user to see
their work done on the computer.
• Two types of monitor are Liquid
Crystal Display and Cathode Ray Tube.

8. Mouse, the smallest
component
•It is a pointing device which
allows the user to point the
cursor and select information
on the computer.

9. Keyboard, the typing device
• The keyboard is a device used to
type in information to the computer.
• It enables the use to do work faster
than having their work written.
• QWERTY Keyboard.

10. Scanner
• The scanner is an additional
device which enables the user to
input their hard copies such as
paper documents and pictures
into the computer as soft copies.

11. Printer
• The printer is also an addition
device which enables the user
to print out soft copies such as
documents and pictures as
hard copies.

12. Speakers
• Speakers are also additional
devices which allow the user to
hear sounds from the computer.
• They are used to play music,
playing movies and etc.

13. Conclusion
• In this presentation, I have established the
significance of having all the computer
components in the installments.
• A single component has its own importance
and function in the computer.
• Without these devices, the computer won’t
actually work or otherwise will not function
properly.
