3. Computer system can be
broken down into two
basic elements, the
hardware and the
software.

5. HARDWAR
E
- is all the
physical
equipment
that makes up
the computer
system.

6. The hardware is the
physical equipment that
makes up the computer
system. It is divided into
system hardware and
peripherals.

7. HARDWARE
HARDWARE
• Hardware, as the name
suggests, is simply a physical
part and tangible component of
a computer system that can be
seen and touched as well as is
mostly required by the
computer system to function or
work.
PERIPHERALS
• Peripherals, as the name suggests,
are simply devices that are used to
be added to computers to expand or
increase their abilities as well as
enhance their features and
functionality and are connected
directly to computers or other
digital devices.

8. HARDWARE
HARDWARE
•keyboard,
•Monitor
•Primary storage
memory (RAM)
•Secondary storage
memory
PERIPHERALS
•Disk drives
•Mouse
•Digitizers
•Printers/plotters

9. SYSTEM UNIT
•The main part of a
microcomputer, is
sometimes called the
chassis. It includes the
following parts:
motherboard,
microprocessor, memory
chips, buses, ports,
expansion slots and

10. CENTRAL
PROCESSING
UNIT (CPU)
is the brain of
the computer
where most of
the “computing”
takes place.

11. KEYBOAR
D
– is the principal device
for communicating with
your computer. All
keyboards have letter
keys, punctuation keys,
and a space bar which
is similar to the keys on
a typewriter. Keyboards
also have functions,
numeric and arrow keys
in additional to Alt,

12. MONITOR
• it has a screen that
displays information, such
as the instruction you send
to your computer and the
information and results your
computer sends back after
interpreting your instruction.
A color monitor will not
display color unless there is
a video card fits inside your
computer. The video card
determines the screen
resolution and the number

13. Hard Disk Drive (HDD) –
it also known as hard
drive. It is a magnetic
storage device that is
installed inside the
computer. The hard drive
is used as a permanent
storage for data. In a
Windows computer, the
hard drive is usually
configured as the C:
drive and contains the
operating system and

14. 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).

15. Mouse – is a small
hand-held device used
to control the
cursor/crosshair on
the screen. They can
be used to select an
item by pointing to it
and clicking a button.

16. Digitizer Tablet – is a
graphics drawing tablet
used for sketching new
images or tracing old
ones. It is also called a
"graphics tablet," where
the user writes or draws
on the surface of the
device with a wired or
wireless pen or puck.
Often, mistakenly called
a mouse, the puck is
officially the "tablet

17. Printer – It is an
output device
that used to
print
information
processed by
your computer.
Printers and
plotters varies
in speed and
output

18. Plotter – an output
device able to
produce better
quality drawings
as compared to
printer, however
the speed of
plotter is
generally slower
than printer.

19. SOFTWARE
IS THE SET OF PROGRAMS AND OTHER RELATED
APPLICATIONS ASSOCIATED WITH A COMPUTER SYSTEM.

20. THE SOFTWARE IS THE SET OF PROGRAMS,
PROCEDURES, AND RELATED DOCUMENTATION
ASSOCIATED WITH A COMPUTER SYSTEM. A
PROGRAM IS A CODED SET OF INSTRUCTIONS
THAT INTERPRETS THE INFORMATION GIVEN
TO THE COMPUTER WITH THE KEYBOARD OR
MOUSE AND DIRECTS THE COMPUTER TO
CARRY A TASK.
SOFTWARE CAN BE CATEGORIZED INTO TWO
MAIN GROUPS: OPERATING SYSTEM SOFTWARE
AND APPLICATION SOFTWARE.

21. OPERATING
SYSTEM
SOFTWARE
The operating system
software provides
various levels of
interaction (called
interface) between the
computer and the
user, as well as
between the computer
and the application
software.

22. APPLICATION
SOFTWARE
The application software
also called programs,
has a specific use or
task to perform such as
AutoCAD for
Architectural drawings
and layouts, Lotus 1-2-
3 for business and
marketing, Adobe
Photoshop for image
