What means of UPS?

Answer 1

A UPS will condition your power going to a computer so that its always the right voltage, thus making your parts last longer. It will also protect it from surges and power outages from anywhere from 30mins to 1hour long.

Answer 2

If you're talking about computers, UPS stands for uninteruptable power supply. A UPS provides power in the case of a power outage. The level of protection depends on the individual power supply, and most simply provide a few minutes worth of power so you have time to properly shut down your computer to avoid data loss. I've also seen a UPS system that had a 1 hour battery for the entire building (all computers and minimal lights) and 2 diesel train engines that could be turned on to provide full power to the building for days. (as a side note, the company had to call and warn the fire department before starting up the engines because of the plume of black smoke that would billow out of the building making people think there was a massive fire.)

EDIT: UPS is also an American parcel courier.
