Hardware Engineering
Introducation
- Computer Hardware is the physical components of the computer, Refers to the tangible (things you can touch) components of a computer system.
Hardware Components
- Hardware components are
further divided into three groups.
- Input Devices
- Output Devices
- System Unit
- Input Devices
- Output Devices
- System Unit
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
INPUT DEVICES
- Keyboard
- Is a standard input device of most computers.
Used to type data into the computer
- Mouse
- Is a hand-clicked
device used for
pointing and moving
objects
- Joystick
- Is an input device which
is commonly used for
computer games
- Light Pen
- A device used to draw,
write, or issue
commands when it
touches a specially
designed screen
- Track Ball
- Basically an upside
down mouse
- Scanner
- A scanner allows you to
scan documents,
pictures, or graphics
and view them on the
computer.

OUTPUT DEVICES
- Inkjet Printer
- Laser Printer
- Impact Printer
- Printers
- An output device that produces
text and graphics on paper
- Monitor
- The monitor is used to provide soft
copy output.
- Multimedia Projector
- Is a type of video projector
for displaying video,
images or computer data
on a screen or other flat
surface
- Speaker
- Play sounds transmitted
as electrical signals from
the sound card.

SYSTEM UNIT
- Motherboard
- The motherboard is the
main circuit board of a
microcomputer. It is
also known as the mainboard or system
board
- IDE SATA
- IDE stands for
Integrated Device
Electronics. is a
standard electronic
interface used
between a
computer
motherboard and
the computer's disk
storage devices
- Hard-Disk Drive
- is a storage device
that store billons of
characters of data
on a nonremovable
disk
- CPU
- 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
- 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.
- Memory
- The memory in a computer system is of two
fundamental types: The main/primary memory and
the secondary memory.
- Primary Memory
- RAM
- Secondary Memory
- HDD
- Floppy Disk Drive
- Used to stores and
retrieves
information on a
floppy disk
- CD/DVD Drive
- is a device that reads
information stored on a
compact disc, it is a
storage device that use
laser technology to read
data from optical disks.
- Video Card
- is a board that
is plugged into
a computer to
give it display
capabilities.
- Sound Card
- enhances the
computers sound
generating
capabilities by
allowing sound to be
output through
speakers
- Modem
- A modem is a
device that sends
and receives data
over telephone
lines to and from
computers.
