What is the main difference between a UPS and the computer's normal power supply unit?

Answer and explanation

Correct answer: A UPS provides external backup power while a PSU distributes power inside the computer

The governing concept is the distinction between backup power and internal power conversion. A UPS supplies temporary external power when the mains supply fails, giving time to save work or shut down safely. A PSU is installed inside the computer and converts incoming electricity into suitable voltages for components such as the motherboard and drives. Therefore option C is correct; the other choices confuse power devices with storage, processing, or networking.
