To keep a desktop computer or a server powered up when the electricity goes off in addition to protection against power fluctuations, an uninterruptible power supply (UPS), which contains a built-in battery, can be used.

Explanation:

An uninterruptible power supply (UPS) is a device that allows a computer or server powered up for a short time, when the electricity goes off. UPS device also provides uninterrupted service during power fluctuation.

A battery is inbuilt in the UPS and provides power for few minutes to the computer to shut down it in a proper manner.

UPS is available at affordable cost and can be maintained at low cost compared to generators.

To keep a desktop computer or a server powered up when the electricity goes off in addition to protection against power fluctuations, an UPS, which contains a built-in battery, can be used.

An uninterruptible power supply (UPS) is a thing that enables a computer to continue working for at least a little time when the prime power source is dropped. UPS devices also shield from power breakers.

A UPS comprises a battery that "potencies in" when the machine senses a loss of potential from the primary source.  When all power drops out, any data in your computer's random access memory is eradicated. When power breakers transpire, a UPS prevents the surge so that it does not corrupt the computer.
