Rather than running a computer for a long time, what is an uninterruptible power supply mainly useful for?

Answer and explanation

Correct answer: To provide time to save work and shut down safely

An uninterruptible power supply, or UPS, supplies electricity for a limited period after the mains power fails and may also smooth brief voltage changes. Its main practical purpose is to keep the computer running long enough to save work and perform a safe shutdown, reducing data loss and hardware stress. Thus, option D is correct; it is not an internet, CPU, or file-compression device.
