Uninterruptible power supply

An uninterruptible power supply (or "UPS") is a type of device that helps your devices, like a computer or a TV, stay on even when there is an interruption in the power. Think of it like a very big battery that can keep your devices running for a short time. UPSs have a very powerful battery that can supply electricity to your devices during a power outage or even a voltage surge. That means when the power goes out, the UPS instantly kicks in and supplies power to your devices so that you don't lose any data. So in short, an uninterruptible power supply is like a big battery that keeps your devices on even when the electricity goes out.
