This document summarizes computer hardware components. It divides hardware into three main groups: input devices, output devices, and the system unit. Input devices like keyboards and mice are used to enter data, while output devices like monitors and printers display or print data. The system unit contains the central processing unit and memory that process data, as well as components like the motherboard, hard disk drive, power supply, and expansion cards.

1. Computer Hardware

2. Computer Hardware
is the physical components of
the computer, Refers to the
tangible (things you can
touch) components of a
computer system.

3. Hardware components are
further divided into three groups.
1. Input Devices
2. Output Devices
3. System Unit

4. INPUT DEVICE
An input device lets you communicate with a computer. You can
use input devices to enter information and issue commands.
OUTPUT DEVICE
An output device displays information on a screen, creates
printed copies or generates sound.
SYSTEM UNIT
The system unit is the part of the computer which is responsible
for accepting and processing the data brought in by the input
devices

5. INPUT
DEVICES

6. Keyboard
Is a standard input device of most computers.
Used to type data into the computer.

14. SYSTEM
UNIT

15. Motherboard
Hard-Disk Drive
IDE
The motherboard is the
main circuit board of a
microcomputer. It is
also known as the
mainboard or system
board
is a storage device
that store billons of
characters of data
on a nonremovable
disk
SATA
IDE stands for
Integrated Serial Advanced
Device
Electronics. Technology
is a
standard Attachment
electronic
interface used
between a
computer
motherboard and
the computer's disk
storage devices

16. Ports
Power Sockets
a PS/connection 2 Keyboard from the main PS/2 circuit
Mouse
board USB Ports
to a peripheral device such as a
Parallel (Printer) Port
keyboard, a printer or a video
monitor. The port is also called Game Port
an
interface. Ports are arranged at the
rear of the main circuit board.
USB Ports
Ethernet (RJ-45) Port
COM (Serial) Ports
Sound Card Slots
GREEN - Speaker / Headphone
BLUE - CD Player / Ipod / etc.
PINK - Microphone
VGA (Monitor) Port

17. The central processing unit
carries out each instruction of
the program in sequence, to
perform the basic arithmetical,
logical, and input/output
operations of the system
CPU
Power Supply
it supplies power from the
power supply to the drive. The
power cables are red, yellow and
black. The yellow wire furnishes
12 volts of power, the red wire
furnishes 5 volts of power, the
two black wire are ground wire
for each.

18. Memory
The memory in a computer system is of two
fundamental types: The main/primary memory and
the secondary memory.
Primary Memory Secondary Memory
RAM HDD

19. Used to stores and
retrieves
information on a
floppy disk.

is plugged into
a computer to
give it display
capabilities.
enhances the
computers sound
generating
capabilities by
allowing sound to be
output through
speakers.

device that sends
and receives data
over telephone
lines to and from
computers.
