A UPS is a device that continually monitors the power to a computer system and maintains the charge on an internal battery. If the power is interrupted, the UPS provides backup power to the system without interruption. The backup power comes from a battery inside the UPS and can only power the computer system for a short period of time. UPS’s are designed to provide the end-user with sufficient time to properly shut down a computer system should the main power fail. A UPS can also provide an even flow of power to the computer and prevent damage caused by voltage surges.
UPS’s suitable for home and small business use are relatively inexpensive and often incorporate surge suppressors and other functionality to stabilise the power supplied by the utilities company. It is highly recommended that all computers be protected by a UPS regardless of their functionality or location.
