Which external component is useful for keeping a computer running during a short power interruption?

Answer and explanation

Correct answer: Uninterruptible power supply

The governing concept is short-term power backup. An uninterruptible power supply, or UPS, contains a battery and changes to battery power when the main supply fails, allowing the computer to continue briefly and giving the user time to save work and shut down safely. A joystick controls games, a webcam captures video, and a graphics card processes images; none supplies backup electricity. Therefore, option C is correct.
