Some customers own a UPS system which is a backup power supply to keep them from experiencing even momentary outages. What does UPS stand for?

• A. Universal power source
• B. Universal power supply
• C. Uninterrupted power supply
• D. None of the above

Answer: (C)

The key idea is recognizing what UPS stands for and how it functions. A UPS is an Uninterruptible Power Supply. It’s designed to keep equipment running without any noticeable interruption when the incoming power fails or drops, using stored energy in batteries (and sometimes capacitors). This allows time to save work, shut systems down safely, or switch to another power source without a sudden outage. In addition to bridging outages, many UPS units also condition the power to protect against surges and electrical noise. The other options describe generic power sources or supplies, but they don’t convey the continuous, interruption-free capability that defines a UPS.
