4. MEANING :- Input devices are peripherals you can attach to your
computer that allow it to receive input from a user. Most
computers come standard with two universal input devices: the
keyboard and the mouse. Other input devices include game
controllers, such as joysticks and game pads, web cams and
microphones, scanners and digital cameras. Computers rely on
data from input devices; without input devices, a computer
cannot receive any information from the user and cannot be
operated.
FUNCTION :- Input devices refer to devices such
as mice, keyboards, webcams and the
microphone. Their main function is to allow the
user to control the machine through data input.
They are also a medium through which the user
communicates with the computer.

5. EXAMPLES OF INPUT DEVICE
It can be used for shortcuts, like copy,
paste, empty trash, etc. It is also used
for answering this question. It has many
uses such as type writing ...not just
typing but typing with fast speed that
consume a lot of time. keyboard also
very helpful in Dos command which is
one of the best security system where a
mouse can't work.
In computing, a mouse is a pointing device that
functions by detecting two-dimensional motion relative
to its supporting surface. Physically, a mouse consists of
an object held under one of the user's hands, with one
or more buttons.
The mouse sometimes features other elements, such as
"wheels", which allow the user to perform various
system-dependent operations, or extra buttons or
features that can add more control or dimensional input.
The mouse's motion typically translates into the motion
of a pointer on a display, which allows for fine control of
a graphical user interface.

6. MENING OF OUTPUT DEVICE:-
An output device is any device used to send data from a
computer to another device or user. Most computer
data output that is meant for humans is in the form of
audio or video. Thus, most output devices used by
humans are in these categories. Examples include
monitors, projectors, speakers, headphones and
printers.
FUNCTION OUTPUT DEVICE:-
Out put devices refers to those
peripherals which gives you the result of
a processed input. It can be images on a
screen, vibration from a joy pad, print
out.

7. Headphones are a pair of small loudspeakers that are
designed to be held in place close to a user's ears.
Headphones either have wires for connection to a signal
source such as an audio amplifier, radio, CD player,
portable media player or mobile phone, or have a
wireless receiver, which is used to pick up signal without
using a cable. They are sometimes known as ear
speakers or, colloquially, cans.[2] The alternate in-ear
versions are known as earphones or ear buds. In the
context of telecommunication, a headset is a
combination of headphone and microphone
Radio is the wireless transmission of signals through free
space by electromagnetic radiation of a frequency
significantly below that of visible light, in the radio
frequency range, from about 30 kHz to 300 GHz.[1] These
waves are called radio waves. Electromagnetic radiation
travels by means of oscillating electromagnetic fields that
pass through the air and the vacuum of space.
Information, such as sound, is carried by systematically
changing (modulating) some property of the radiated waves,
such as their amplitude, frequency, phase, or pulse width.
When radio waves strike an electrical conductor, the
oscillating fields induce an alternating current in the
conductor. The information in the waves can be extracted
and transformed back into its original form.

8. FUNCTION OF STORAGE DEVICE:-
Storage devices save all of your computer's
permanent information. Things that you download,
your preferences and settings, programs and
games that you have installed, your operating
system, etc. are all installed on your hard
drive. When your computer needs to load
something, it searches through your HDD to locate
the files that it needs. Without storage devices,
your computer would not function and would be
unable to go beyond the BIOS screen when
booting.

9. CD-ROM drives are very popular for playing
and installing media. CD-ROM drives are
classified as 5.25-inch drives because they fit
into the 5.25-inch drive bays that are used in
computer cases. CD-ROM drives come in many
forms, including external, internal, and more.
DVD stands for Digital Versatile (or Video) Disc.
It is used for storing information in digital form
