An input device provides data and control signals to a computer. Examples include keyboards, mice, scanners, cameras, joysticks, and microphones. A microphone converts sound into electrical signals while a mouse controls cursor movement and selection. Other input devices described are light pens, which allow screen pointing and drawing, and joysticks, which report directional movement. Output devices convert information into human-readable form like text, graphics, audio and video. Examples are computer monitors that display images, speakers that generate sound, plotters that print vector graphics using pens, and printers that transfer information to paper.

3. WHAT IS INPUT DEVICE ?
• An input device is a piece of equipment
used to provide data and control signals
to an information processing system such
as a computer or information appliance.
Examples of input devices include
keyboards, mouse, scanners, cameras,
joysticks, and microphones.

4. DIFFERENT TYPES OF INPUT DEVICES:-
M I C R O P H O N E
• A microphone, colloquially
called a mic or mike
(/maɪk/), is a device – a
transducer – that converts
sound into an electrical
signal. ... Several types
of microphone are used
today, which employ
different methods to
convert the air pressure
variations of a sound wave
to an electrical signal.

• A computer mouse is a
handheld hardware input
device that controls a
cursor in a GUI and can
move and select text, icons,
files, and folders. For
desktop computers,
the mouse is placed on a
flat surface such as
a mouse pad or a desk and
is placed in front of your
computer

L I G H T P E N
• A light pen is a computer
input device in the form of
a light-sensitive wand
used in conjunction with a
computer's cathode-ray
tube (CRT) display. It
allows the user to point to
displayed objects or draw
on the screen in a similar
way to a touchscreen but
with greater positional
accuracy.
J O Y S T I C K
• A joystick is an input
device consisting of a
stick that pivots on a
base and reports its
angle or direction to
the device it is
controlling. ... Joysticks
are often used to
control video games,
and usually have one or
more push-buttons
whose state can also be
read by the computer.

8. WHAT IS OUTPUT DEVICE ?
• An output device is any piece of computer
hardware equipment which converts
information into human-readable form.
It can be text, graphics, tactile, audio,
and video. Some of the output devices are
Visual Display Units (VDU) i.e. a Monitor,
Printer, Graphic Output devices, Plotters,
Speakers etc.

9. DIFFERENT TYPES OF OUTPUT DEVICES:-
M O N I T O R
• A computer monitor is an
electronic device that shows
pictures for computers.
Monitors often look similar
to televisions. The main
difference between
a monitor and a television
is that a monitor does not
have a television tuner to
change channels. Monitors
often have higher display
resolution than televisions.
S P E A K E R S
• A speaker is a term used
to describe the user who is
giving vocal commands to
a software program. ... A
computer speaker is an
output hardware device
that connects to a
computer to generate
sound. The signal used to
produce the sound that
comes from a
computer speaker is
created by the computer's
sound card

• A plotter is a computer
hardware device much
like a printer that is
used for printing vector
graphics. Instead of
toner, plotters use a
pen, pencil, marker, or
another writing tool to
draw multiple,
continuous lines onto
paper rather than a
series of dots like a
traditional printer.
P R I N T E R
• A printer is a device that
accepts text and graphic
output from a computer
and transfers the
information to paper,
usually to standard size
sheets of
paper. Printers vary in
size, speed,
sophistication, and cost.
In general, more
expensive printers are
used for higher-resolution
color printing.
