Which device is used to input data into a computer or other device?

• A. Output
• B. ROM
• C. Input
• D. RAM

Answer: (C)

Input devices are used to bring data into a computer, turning keyboard strokes, mouse movements, voice, or scanned images into digital information the system can process. That makes the option describing input the best choice. In contrast, output devices like monitors or printers display results from the computer; ROM holds non-volatile firmware data that doesn’t get entered during normal operation; RAM is volatile memory used to store data temporarily while the CPU works on tasks, not specifically for input.
