8. The following list represents a basic set of
devices found in most Personal Computers.
1. System Unit- The main part of a
microcomputer, sometimes called the chassis.
-Parts of computer that houses the primary
devices.
-It includes the following parts: Motherboard,
Microprocessor, Memory Chips, Buses, Ports,
Expansion Slots and Cards.

10. 2. Motherboard / Mainboard / System Board- The
main circuit board of a computer. It contains all the
circuits and components that run the computer.

11. 3. CPU (Central Processing Unit) - The processor is
the main “brain” or “heart” of a computer system.
It performs all of the instructions and calculations
that are needed and manages the flow of
information through a computer.

12. 4. Primary storage- (internal storage,
main memory or memory) is the
computer's working storage space that
holds data, instructions for processing and
processed data (information) waiting to be
sent to secondary storage. Physically,
primary storage is a collection of RAM
chips.

13. Two (2) Types of Memory
ROM – (Read Only Memory) ROM is non-
volatile, meaning it holds data even when
the power is ON or OFF.

15. Two (2) Types of Memory
RAM – (Random Access Memory) RAM is
volatile, meaning it holds data only when
the power is on. When the power is off,
RAM's contents are lost.

16. Examples of RAM

17. 5. Expansion Bus
A bus is a data pathway between several hardware
components inside or outside a computer. It does not
only connect the parts of the CPU to each other, but
also links the CPU with other important hardware

19. 6. Adapters- Printed-circuit boards (also called
interface cards) that enable the computer to use
a peripheral device for which it does not have
the necessary connections or circuit boards.
They are often used to permit upgrading to a
new different hardware.

10. Power supply
7. Power Supply Unit (PSU) - Installed in the back
corner of the PC case, next to the motherboard. It
converts 120vac (standard house power) into DC
voltages that are used by other components in the PC.

22. 8. Hard Disk Drive (HDD) - Also known as hard drive, is a
magnetic storage device that is installed inside the computer.
The hard drive is used as permanent storage for data. In a
Windows computer, the hard drive is usually configured as the
C: drive and contains the operating system and applications.

24. 9.Digital Versatile Disc (DVD) - Designed to
optically access data stored on a DVD. A laser
moves back and forth near the disk surface and
accesses data at a very fast rate.

25. 10. Optical Drive- An optical drive is a storage
device that uses lasers to read data on the
optical media. There are three types of optical
drives: Compact Disc (CD), Digital Versatile Disc
(DVD) and Blu-ray Disc (BD).

26. What is system unit?
How many computer devices that we had
discussed? Enumerate them?
What is RAM and ROM?
What is the importance of knowing the
different roles of those devices?

27. What do you think will happen if you didn’t know
each role and you are using the computer?
Like the different device, they have important
roles in the computer. What is you role as a part
of the technological world or generation?
If you will be a part of the computer, what will it
be and why?
In the rural area, do you think they have already
computer today? Does the IP people already
know how to use the computer?

28. Direction: Identify the following the most basic devices in
computer. Write letter of the correct answer.
1. Which of the following is the data pathway between
several hardware components inside or outside a computer.
A. CPU B. RAM c. ROM D. Expansion Bus
2. Teacher Joan is doing his work in the computer and
suddenly the power is off and she forgot to save his work.
When she turns on the computer she is very thankful that
the data is still there. Which of the following holds the
data?
A. CPU B. RAM c. ROM D. Expansion Bus

29. 3. It performs all of the instructions and calculations
that are needed and manages the flow of information
through a computer.
A. Central Processing unit B. Mother Board
 C. Hard disk drive D. Power supply unit
4. Which f the following is the main circuit board of a
computer. It contains all the circuits and components
that run the computer.
A. Central Processing unit B. Mother Board
C. Hard disk drive D. Power supply unit

30. 5. Which of the following is usually configured as the
C: drive and contains the operating system and
applications.
A. Central Processing unit C. Mother Board
B. Hard disk drive D. Power supply unit
