Correct answer: C
Correct answer: Input devices convert human-understandable instructions and data into a form that computers can understand and process.
How input devices work: Input devices capture user actions (typing, clicking, speaking, scanning) and translate them into electrical signals and digital codes (binary) that the computer's hardware and software can interpret.
Common examples: keyboard converts keystrokes to key codes; mouse converts movement and clicks to pointer events; scanner converts printed images to digital image files; microphone converts sound to digital audio data.
Why other devices are not correct: Printers, monitors, and other output devices convert computer data into human-understandable form (printed pages, on-screen images, or sound). They perform the opposite direction of conversion required by the question.
