Protecting Computer Systems From Power Outages
Computer systems and other electronic devices containing logic circuitry are susceptible to data loss or hardware damage that can be caused by the sudden loss of power. These can include data networking equipment, video projectors, alarm systems as well as computers. To protect against this, the use of an uninterruptible power supply or UPS can provide a constant flow of electricity in the event that a primary power supply becomes unavailable for a short period of time. To protect against surges (events where voltages increase for a few seconds), which can damage hardware when power is restored, a special device called a surge protector that absorbs the excess voltage can be used.

Famous quotes containing the words protecting, computer, systems and/or power:
“The manufacturing corporation, except in comparatively few instances, no longer represents a protecting care, a parental influence, over its operatives. It is too often a soulless organization; and its members forget that they are morally responsible for the souls and bodies, as well as for the wages, of those whose labor is the source of their wealth.”
—Harriet H. Robinson (1825–1911)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
“The obligation of subjects to the sovereign is understood to last as long, and no longer, than the power lasteth by which he is able to protect them.”
—Thomas Hobbes (1588–1679)
