OUTPUT DEVICES
Output devices are pieces of computer
hardware that allow a computer system to
communicate information to a user or another
system. This information can be in any form,
and includes sound, images, and even tactile
experiences. Output devices can usually only
be used to send data from the computer; items
called input devices allow users and other
systems to send data to the computer.

CATEGORIES OF OUTPUT
DEVICES A hard copy is a type of material suitable for
direct use, meaning that the user can read the
material directly, rather than having to process
it through a computer or some other technology.
The most classic example is printed material on
paper. Many industries that work heavily with
electronics use the term, along with

others, to distinguish what type of media is
being discussed. It is sometimes also called a
permanent reproduction, since it does not
change once it has been generated.
A soft copy is an electronic copy of a
document. It contrasts with a hard copy, a
document printed out on paper or another
medium.

Soft copies are easy to transfer, distribute,
share, and manipulate all potential
drawbacks or advantages, depending on
the document involved.

THE MONITOR
A monitor is also called video display terminal
(VDT). The users can view the visual display of
the processed data on the monitor. Computer
monitors come in a variety of screen sizes and not
to forget, visual resolutions. All monitors have a
video card, which processes the data into images,
to be eventually displayed. Continues….

Cathode Ray Tube (CRT) and flat panel
displays are the two types of monitors.
CRTs are cheaper, and have good viewing
angle. They are also bulkier and consume
more power. On the other hand, the flat
panel displays have no magnetic
interference and lighter. They are also
costlier. HOME

PRINTER Printer is an external hardware device, which
takes processed data from the computer to
generate a hard copy of the same. After the
monitors, printers are the most used
peripherals of computers and they are
commonly used to print text data, images, etc.
There are three main types of computer
printers, namely inkjet, laser and Continues….

dot matrix printers. The dot matrix printer is an
impact printer. It uses striking pins against a
ribbon to produce the characters in order to
print the data. The inkjet printer uses
magnetized plates that spray ink on the paper
to produce the data. On the other hand, laser
printers use a laser beam to produce the data.

SPEAKER A speaker is a hardware device, that is
connected to a computer's sound card, which
outputs the sound generated by the card.
Audio data generated by the computer is sent
to the audio card that is located in the
expansion slot. The card translates the data
into audio signals, which are then sent to

either the speakers or the headphones.
In the initial phase, computers had on-board
speakers, which generated series of different
tones and beeps. When the popularity of
multimedia and computer games grew, better
quality computer speakers known for higher
quality sound effects and music came into the
market.
