What is a UPS?

An uninterruptible power supply (UPS) is primarily used to provide a backup power source to the parts in the computer case, the monitor and any other device plugged in to the UPS. It is like a short term battery that prevents your computer from immediately switching off in case of a power cut. A UPS keeps your computer running for a short wile. So when a power cut occurs, you will still have time to save your data and to properly shut down your computer. In addition to acting as a backup when the power goes out, most UPS devices also act as power "conditioners" by ensuring that the electricity flowing to your computer and accessories is free from drops or surges. If a computer is not receiving a consistent flow of electricity, damage can and often does occur.;
