Input Devices and Output Devices | Detailed Summary

Input devices and output devices are two types of peripheral devices that are used to interact with a computer or other electronic device. Input devices are used to input data, commands, and other information into the computer, while output devices are used to communicate information to the user.

What are Input Devices?

Input devices include hardware components such as a keyboard, mouse, touchpad, joystick, trackball, graphics tablet, microphone, scanner, camera, and barcode reader.

These devices allow users to input data, commands, and other information into the computer, which is then processed by the central processing unit (CPU). Keyboards, for example, are used for typing text and numbers, while mice are used to navigate the graphical user interface (GUI) of a computer.

What are Output Devices?

On the other hand, output devices include hardware components such as a monitor, printer, speaker, headphones, projector, plotter, Braille display, tactile graphics display, smartwatches and fitness trackers, and virtual reality headsets.

These devices take the data and instructions processed by the computer’s CPU and convert them into a form that can be easily understood by the user. Monitors, for example, are used to displaying the output of a computer, while printers are used to print documents, photographs, and other materials.

Conclusion

In summary, input devices are used to input data into the computer and output devices are used to communicate information to the user. While input devices are used to control and give commands to the computer, output devices are used to display or present the results of the computer’s processing. Both types of devices are essential for the functioning of computers and other electronic devices, and the choice of device depends on the specific needs and requirements of the user.
