What is UPS?

Explanation:
A UPS, or uninterruptible power supply, is a battery-powered device that provides immediate backup power when the main power fails and also conditions and protects against voltage surges and sags. This keeps critical equipment running long enough to prevent data loss and to shut down safely or switch to a backup system. It differs from a back-up generator, which supplies power for longer periods but usually requires fuel, startup time, and isn’t instant; it also isn’t a solar panel, which generates electricity from sunlight, nor a data storage device, which stores information.
