What is “UPS”?

Monday, November 22nd, 2004 by | Filed Under: Computer Terms

What is “UPS”?

Well, if you need to ship a package across the country, around the world, or down the street, you might choose UPS as your carrier. The United Parcel Service began in 1907 by 19-year-old James E. Casey, who delivered packages via bicycle! He and his brother, George, then expanded their business to…

Oh, wait! You probably want the computer term “UPS” seeing as this is a Computer Tips newsletter.

Well, in that case, UPS stands for Uninterruptable Power Supply. This is a back-up power supply that provides power to a system in the case of a drop in voltage or a power outage.

In the case of small or private systems, this usually consists of a battery power supply that will last several minutes, allowing the user to save their work and shut down the system in a proper fashion. This helps protect whatever they may have been working on and the files of any application that may happen to be running.
