Input Device vs. Output Device — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 20, 2023
An Input Device sends data to a computer for processing, like a keyboard, while an Output Device displays or produces results from the computer, like a monitor.

Key Differences
An Input Device is any hardware component that provides data to a computer system for processing. This can include devices like keyboards, mice, and scanners. Conversely, an Output Device is a piece of hardware that receives processed data from the computer to present it to the user or another system. Examples are monitors, printers, and speakers.
The primary role of an Input Device is to allow users to communicate or command the computer system. This communication is achieved by entering data or commands. On the other hand, an Output Device takes this processed data and presents it in a form that's interpretable by users or other systems, ensuring feedback from the computer system.
When considering the flow of information, an Input Device is the starting point, capturing raw data. This data undergoes processing within the computer system. Post processing, the Output Device serves as the endpoint, delivering the results.
It's essential to understand that while some devices clearly fall into one category, there are devices that can function as both an Input Device and an Output Device. For example, a touchscreen can take inputs when you touch it and display outputs as a screen.
Interactivity is a key aspect in modern computing. While Input Devices ensure users can interact with systems, provide commands, and input data, Output Devices enable systems to give feedback, produce results, and communicate back to the users or other systems.
