This document defines and describes the major internal and external hardware components of a computer system. It discusses the internal components including the motherboard, processor, RAM, hard disk drive, CD-ROM drive, power supply, graphics card, solid state drive, and fan. It also discusses the external components, which include the monitor, keyboard, mouse, computer casing, and printer. For each component, it provides a brief explanation of its function within the computer system.

3. What is hardware?
●
Computer hardware is
the collection of
physical elements that
constitutes a computer
system.

5. The motherboard
•
•
Printed circuit
board.
Houses most
internal
components.

6. The processor
•
•
Carries out instructions
given by computer
programs.
Handles all the day to
day tasks that a PC has
to do.

7. RAM
●
●
It deals with temporary
data requests such as
keeping windows open.
The more RAM you
have, more windows
and processes can be
open.

8. Hard disk drive
●
●
Data is retrieved by
using a series of disks
that store the data.
The spindle writes the
data to the magnetic
disk.

9. CD-Rom drive
●
●
They use laser beams
to read the data on the
disc.
Drives like this one
connect to the
motherboard via SATA
cables.

10. Power supply
●
Converts mains AC
electricity into DC
electricity that powers
all the internal
components.

11. Power cable
●
Are connected to the
Power Supply Unit and
cables that look like
this power the
motherboard and is the
largest connector found
on a PC’s motherboard.

12. FAN
●
Sucks cool air into the
PC case, blows hot air
out of the case and
stops any key
components
overheating.

13. Graphics card
●
They processes and
produces outputs for
displays. These are a
crucial component that
monitors rely on. They
also handle output of
video to projectors.

14. Solid state drives (SSD)
●
They are a form of
computer data storage.
They are faster than
traditional hard disks,
but they have less
storage.

16. Monitor
●
It is the display for a
PC where anything you
can see is displayed.
They connect to your
PC through a DVI or
HDMI cable attached
to the graphics card.

17. Keyboard
●
It is the main way of
typing on a PC. They
vary depending on
what they are used for.
Keyboards connect to a
PC wirelessly or use
USB cables.

18. Mouse
●
It's the primary way of
navigating a computer.
The mouse used to
have a ball that could
move in any direction.
Now, They have infra
red lasers.

19. Computer Casing
●
It's the housing for the
internal components.
They are quite bulky.

20. Printer
●
It's computer hardware
that will print anything
created on a PC onto
paper, whether it be
text or photos. They
