Electricity

Desktop Computers need power from a direct source to operate. Laptops and
notebooks operate with batteries which need to be recharged when it runs down.
Electric power especially from the direct source is not always reliable.
Fluctuations and frequent electric power failures and faults are threats that can
damage computers. UPS, voltage guards and regulators are used to protect
computers and other appliances from electric faults.
UPS stands for Uninterruptible Power Supply. UPS is used to ensure

constant supply of electric power to the computer system and
also used to sustain power for some time when the mains goes

off. In other words, it's a gadget that provides emergency power to
the computer when electric power fails.

Voltage Regulator (Stabilizer) is a gadget designed to maintain a

the computers and other electronic appliances from power fluctuations.
