Differentiate between input and output inits
Answers
Answer:
An input device sends information for processing, where as an output device would would reproduce or display the results of the processing.
To break this down a monitor, speakers, printer, and light bulb are all samples of output devices. A microphone, mouse, trackpad, joystick, scanner, and keyboard are all examples of input devices.
Additionally, so it's been said, some devices are both input and output, this would be a Rewritable CD/DVD and many USB devices.
An input device sends information to a
computer system for processing, and
an output device reproduces or displays
the results of that processing. Input
devices only allow for input of data to a
computer and output
devices only receive the output of data
from another device.
Most devices are only input devices or
output devices, as they can only accept
data input from a user or output data
generated by a computer. However,
some devices can accept input and
display output, and they are referred to
as I/O devices (input/output devices).
For example, as you can see in the top
half of the image, a keyboard sends
electrical signals, which are received by
the computer as input. Those signals
are then interpreted by the computer
and displayed, or output, on the
monitor as text or images. In the lower
half of the image, the computer sends,
or outputs, data to a printer, which
will print the data onto a piece of
paper, also considered output.
Input devices:-
An input device can send data to
another device, but it cannot receive
data from another device. Examples of
input devices include the following.
Keyboard and Mouse - Accepts input from a
user and sends that data (input) to the
computer. They cannot accept or reproduce
information (output) from the computer.
Microphone - Receives sound generated by an
input source, and sends that sound to a
computer.
Webcam - Receives images generated by
whatever it is pointed at (input) and sends
those images to a computer.
Output devices:-
An output device can receive data
from another device and generate
output with that data, but it cannot
send data to another device. Examples
of output devices include the following.
Monitor - Receives data from a computer
(output) and displays that information as text
and images for users to view. It cannot accept data from a user and send that data to another
device.
Projector - Receives data from a computer
(output) and displays, or projects, that
information as text and images onto a surface,
like a wall or a screen. It cannot accept data
from a user and send that data to another
device.
Speakers - Receives sound data from a
computer and plays the sounds for users to
hear. It cannot accept sound generated by
users and send that sound to another device.
