Output devices convert electronic information into human-readable formats such as audio, visual, and printed documents. Common output devices include monitors, printers, headphones, computer speakers, projectors, GPS, sound cards, video cards, braille readers, speech synthesizers, and plotters, each serving unique functions for displaying processed data. These devices enhance user experience by delivering information in various formats tailored to specific needs.

1. Output devices allow to
convert the electronic
information into the
humans readable format.
This format may be
audio, visual, textual, or
hard copy such as
printed document.

2. There are different types of output devices, which are
used for displaying processed data into various formats;
below explain each one –
1. Monitor
2. Printer
3. Headphones
4. Computer Speakers
5. Projector
6. GPS
7. Sound card
8. Video card
9. Braille reader
10 Speech Synthesizer
11. Plotter

3. The monitor is commonly
used as output device
because it helps to show all
result as the e graphical
form. User requires serving
the power supply to
the computer monitor. The
monitor is getting to link via
VGA cable to CPU (Central
Processing Unit). Monitor
has two elements like as
cathode ray tube and a

4. Printer is a hardware
device that helps to
provide the hard copy
version, after getting of
processed data from
computer. A printer allows
to users for getting output
in the form of text and
graphic format.

5. Headphones are also called the
“Earphone“, and user can plug
headphone with computer,
mobile, and laptop to hear the
voice. Mostly, users use the
headphones to hear the sound
without getting any hindrance to
other person. They are also
output device of computer.
Firstly, Headphone was
developed for using in the US
navy, in 1910.

6. Computer speakers are
output hardware devices,
which are connected with
computer for getting sound.
Computer’s sound card allows
to generate sound with using
of the signals, which come
from speaker.
Commonly, computer
speakers consist the internal
amplifier that allows to
enhance level of volume as
per the need of users.

7. Projector is an output hardware
device that allows to user to project
the output on the big screen, wall, or
other large surface. Projector
enables to light and lenses to
provide magnified text, image, and
videos.
Mostly, projectors are used offices
for showing their presentations at
the front of clients, classrooms,
places of worship, auditoriums, and
watching movies with enabling
group of people.

8. GPS stands for “Global Positioning
System“, and it is a space-based satellite
navigation output hardware device that
helps to calculate the location of your
device. The aim of GPS is to produce the
result related to providing location, weather
conditions, and also tracking.
GPS (Global Positioning System) consists
24 satellites, and it scaled in space about
12000 miles about the earth’ surface.
Today, you can use “Global Positioning
System” in your smart phone, vehicle, and
other tracking devices.

9. Sound card is also called as the “Audio Adapter“, and it is a
expansion card or integrated circuit that is embedded on the
different types of motherboard. Sound card receives the
signals from motherboard then process them, and finally
convert them into audio. It helps to increase the audio
experience. Sound card is very helpful for watching video,

10. Video card is an expansion card that is
embedded on the motherboard, and it
helps to enhance the quality of video
and other graphical content. Video card
allows to increase the experience of
playing game, photo, watching movies,
etc.
Now these days, video card is attached
by default inside the computer, but if
you want to boost up your visual
elements then it can be added as
externally.

11. Braille reader is a electronic hardware device that is very helpful
for blind people for getting to read texts, which are displayed on
the monitor screen.
There are several kinds of Braille reader such as large units of
keyboard size for computer system and small units for tablets
and laptops.

12. Speech synthesizer is a speech
generating device that helps to
convert text to speech.
Speech synthesizer speaks out
loud the commands, which are
inputted by the use in the form
of text.
It is very helpful for individuals
suffering from speech
impairments.

13. Plotter is also hardware
output device that is similar to
printer but it allows to print
wide format materials such as
banners, brochures,
pamphlets, etc.
Mostly, plotters are used in
the engineering and basically
draw a certain image on a
number of straight lines.
