What type of device allows users to interact with a computer?

• A. Output device
• B. Input device
• C. Storage device
• D. Accessory device

Answer: (B)

An input device is specifically designed to allow users to provide data and control signals to a computer. Common examples of input devices include keyboards, mice, touchscreens, and scanners. These devices transform user actions—such as typing, clicking, or tapping—into a format that the computer can process. This interaction is essential for almost all computing tasks, as users cannot communicate with or command the system without the means to input information.

On the other hand, output devices display or convey information from the computer to the user; storage devices are utilized to save data for future access; and accessory devices may enhance or add functionality but do not directly permit interaction with the computer in the same foundational way as input devices. Thus, the role of input devices is crucial for user interaction within the computing environment.
