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.
