Which device category includes items like a webcam and a game controller?

• A. Storage devices
• B. Input devices
• C. Output devices
• D. Processing units

Answer: (B)

Webcam and game controller are examples of input devices. Their job is to bring data from you or the environment into the computer: a webcam captures video that the computer processes, and a game controller converts your button presses and joystick movements into signals the computer can understand. Other categories serve different roles—storage devices save data for later, output devices like monitors display results from the computer, and processing units (the CPU) perform calculations and control operations. Some devices can do more than one thing (like a touchscreen acting as both input and output), but with these items the correct classification is input devices.
