5. Preliminary Activity:
Direction: List five (5) hardware and software you are familiar with.
Write your answer on the bubbles provided below: Boy/Girl Group

6. •Let each group brainstorm with the members
and explain the output they will put on the
bubble.
•A representative(s) from the group will explain in
relation to the things they will put on the bubble
given.(Explanation will answer the question,
“what makes your answer familiar to you and
what can you say on the item written on the
bubble?”)

AND PERIPHERALS
CSS 8 – 4th Quarter

8. Understanding the Computer System
• As an aspiring computer technician, it is very important to know the
different components of a computer system. These are the hardware,
software and peopleware. Each component plays an important role,
without each other computer systems will not work properly.
Hardware - the physical, touchable, electronic and
mechanical parts of a computer system.

9. A. Major hardware components
of a computer system
The following list represents a basic set of hardware found in most PCs.

10. System Unit
The main part of a
microcomputer,
sometimes called the
chassis. It includes
the following parts:
Motherboard,
Microprocessor,
Memory Chips, Buses,
Ports, Expansion Slots
and Cards.

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

12. 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.

13. 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.
Two (2) Types of Memory
• a. ROM – (Read Only Memory)
• b. RAM – (Random Access Memory)

14. ROM –
(Read Only Memory)
ROM is non-volatile, meaning
it holds data even when the
power is ON or OFF.
EEPROM (BIOS) - stands
for electrically erasable
programmable read-only
memory and is a type of non-
volatile memory used in
computers

15. 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. 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.

17. 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.

18. 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)
- Blu-ray Disc (BD).

19. GROUP TASK
• Using the classroom 4 groups, Select at least 3 computer components
and arrange the computer components from most important to least
important.
• Let a representative from the group or the whole group explain in
front of the class and have a brief explanation to support their
answer.
Rubrics for rating: (Indicator 5)
