While working in a computer, the matter which often irritates is – power cut. Particularly, the power cut, at the time of sending E-mails, will lead to loss of files.

UPS supplies power to a computer during the times of power cut and secures the computer from sudden power interruption – which might damage the internal sensitive chips of a computer. The UPS acts as a conveyor of current when there is power supply. If there is no power supply, UPS comes into role and acts as a power supplying source.
