3. OUTPUT DEVICE
A piece of equipment/hardware which gives out the result of
the entered input, once it is processed (i.e. converts data from
machine language to a human-understandable language), is
called an output device.
Or
An output device is any hardware device used to send data
from a computer to another device or user.
For example- Printer, Monitor, etc.

4. TYPES OF OUTPUT DEVICES
 Monitor
 Printer
 Plotter
 Projector
 Speaker
 Headphone
 Soundcard
 Videocard
 GPS

5. IMPORTANCE
 It allow users to better interact with computer
equipment.
 It obtain information from the computer and send
data that has been processed by the computer to
the user.
 It transfer data in human readable forms, like audio,
visual, and hard copy media.
 For example-
o Speaker - Sound being played .
o Monitor - The main output device of a computer. It forms
images by converting electrical energy into light in the
form of tiny dots on the screen called pixels.

6. ADVANTAGES
 Output devices make our work cheaper as we do
not need to print all the files.
 They can produce high-quality texts and can be
magnified.
 Users can recheck the produced results and make
changes to the file or document before printing.
 Some others are -
o Convenience and Flexibility
o Reduced Clutter
o Enhanced Mobility
o Ease of Sharing
o Increased Accessibility

7. DISADVANTAGES
 It can cost more money to produce outputs as we
need paper and ink during the printing, and quality.
 Devices like speakers, when used at high volume,
can cause health issues.
 Devices like monitors, when seen from a small
distance, can cause problems to the eyes.
 Some others are –
o Images fuzzy
o Expensive
o Accessibility issues

8. CONCLUSION
 Output devices connect to the computer via a cable
or wirelessly. Some output peripherals are already
built into laptops. This allows information on a
computer to be viewed, heard, or played back.
 These peripherals differ from input peripherals,
which allow information from the external
environment to enter a device. For example, the
keyboard, the mouse, or the microphone.
 Some peripherals, such as video display terminals
and USB hubs, are both input and output because
they transmit and receive information.
