COMPUTER HARDWARE
6 elements of communication
computer system
• Human being
• Hardware
• Software
• Data / information
• Procedure
• Communication
What is hardware?
• Hardware is best described as a device that
is physically connected to your computer or
something that can be physically touched. A
CD-ROM, monitor, and printer are all
examples of computer hardware.
• Without any hardware your computer would
not exist and software would have nothing to
run on.
5 main function of hardware
• Input
• Processing
• Output
• Storage
• Communication
TYPES OF HARDWARE
INPUT
OUTPUT
Input Device
• Input device is a tool to interpret the
symbol that understand by human being
to the symbol that computer understand
to process.
• Device for entering information into a
computer.
INPUT DEVICE
Keyboard entry Direct entry
Keyboard Entry
Numeric key
Escape key
Data will
be input
into the
computer
using the
keyboard
Function key
Windows key
Space bar key Cursor key
Direct Entry Device
– This device is to create data that can
be read by machine and direct enter to
the CPU.
– Direct entry device is divide to
• pointing,
• scanner and
• voice input device
Direct entry device
– Pointing Devices
• Mouse
• Trackball
• Touch screen
• Digital camera
Direct entry device
• Example:

• Character recognition
Voice Input Device
• This device is change the human voice into
digital code.
• Example :
– microphone
OUTPUT DEVICE
• Output device is a tool to interpret the
code that understand by computer to the
symbol or language that understand by
human being.
• Device for appearing an information from
computer.
Output Device
• Output Devices are divided by 4 :
–Monitor
–Printer
–Plotter
–Voice output device
Types of monitor
CRT – cathode ray tube LCD – Liquid crystal display monitor
Printer
• Printer is a tools for transferring information
onto paper, that is truly external to the other
functions of the computer.
Printer
• 4 types of printer :
