UPS stands for what?

• A. Uninterruptible Power System
• B. Uninterruptible Power Supply
• C. Unintended Power Supply
• D. Universal Power Supply

Answer: (B)

A UPS is a device that provides backup power without interruption when the main power fails. It stores energy in batteries and uses an inverter to keep delivering power to connected equipment, so there's no sudden shutdown. That immediacy is what the term “uninterruptible” captures, setting it apart from a regular power supply. The word “supply” correctly describes its role as the power source feeding the load. While some people loosely call it an uninterruptible power system, the commonly used name for the device itself is Uninterruptible Power Supply. The other options don’t fit because they either describe a different concept (system) or use inaccurate terms (unintended or universal).
