Question

differentiate between input and output devices​

Answer 1

Explanation:

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.

Answer 2

Explanation:

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

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

 USB flash drive - Receives, or saves, data from

a computer (input). Also, the drive sends data

to a computer or another device (output).

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.
