What is the point in a UPS?

It is important to protect sensitive electronic equipment such as computers from fluctuations and cuts in the power as unexpected loss of power can cause permanent damage to components and data loss. A UPS will act as a surge protector, battery backup and generally “smooth” out the power your computer receives and ensure maximum stability. UPS devices are normally found attached to expensive mission critical workstations (such as graphical workstations or CAD machines) or servers where any downtime is unacceptable.
