PARTS OF A COMPUTER
COMPUTER HARDWARE
AND SOFTWARE
HARDWARE - A computer’s hardware includes all
the physical parts of the computer. These are the
parts that we can see and touch. The hardware
components include the Central Processing Unit
(CPU), the keyboard, the monitor and primary
storage memory (RAM), and the secondary storage
memory. Peripherals include disk drives, mouse,
digitizers, printers/plotters, etc.
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 cards.
CENTRAL PROCESSING UNIT (CPU)
• the brain of the computer
where it performs all
instructions and calculations
that are needed to manage
the flow of information. It
holds instructions, data, and
intermediate final results
during processing. It also
receives instructions from
software or computer
programs and executes them.
KEYBOARD
• 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, Ctrl, and
Enter keys.
MONITOR
•a screen that
displays information,
such as the
instruction you send
to your computer and
the information and
results from your
computer sends back
after interpreting
your instruction.
HARD DISK DRIVE (HDD)
• It is known as a hard
drive. A 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
OPTICAL DRIVE
• 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).
MOUSE
• a small hand-held
device used to
control the
cursor/crosshair on
the screen. It is used
to select an item by
pointing to it and
clicking a button.
DIGITIZER TABLET
• 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
cursor."
PRINTER
• It is an output
device that is used
to print information
processed by your
computer. Printers
and plotters vary in
speed and output
capabilities.
PLOTTER
• an output device
that can produce
better quality
drawings as
compared to the
printer, however,
the speed of plotter
is generally slower
than a printer
SOFTWARE
• The software is the set of programs that
make a computer run. Opposite to
hardware, the software is an intangible
parts of a computer. They are sets of
instructions that tell the computer what
to do to come up with the desired result.
The software can be categorized into two
main groups: operating system software
and application software.
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. These are the programs that work
without your intervention. They automatically
open once you boot your computer. Some of
their tasks include loading and running
programs, checking and protecting computers,
and controlling hardware.
Samples of Operating System
APPLICATION SOFTWARE
• The application software is the programs
installed in a computer. It is also called as
programs. These enable you to do different
tasks like typing, making presentations,
editing pictures and videos, and surfing the
internet. It 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 processing, and so on.
TYPES OF APPLICATION SOFTWARE
• WORD PROCESSING SOFTWARE
• SPREADSHEET SOFTWARE
• PRESENTATION SOFTWARE
• MULTIMEDIA SOFTWARE
• WEB BROWSERS
• EDUCATIONAL SOFTWARE
• GRAPHICS SOFTWARE
• FREEWARE
