Input and output devices are essential components of any computer system. Input devices allow users to interact with the computer and provide data, while output devices display or present information to the user.

Input devices, such as keyboards, mice, and scanners, enable users to enter data, commands, and instructions into the computer. Output devices, such as monitors, printers, and speakers, display or present the processed information to the user.

The key difference between input and output devices lies in their direction of data flow. Input devices transfer data from the user to the computer, while output devices transfer data from the computer to the user.

For example, when you type on a keyboard, you are providing input to the computer. The computer then processes this input and displays the results on the monitor, which is an output device.

In summary, input devices allow users to interact with the computer and provide data, while output devices display or present information to the user. The key difference between them is the direction of data flow.
