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“The manufacturing corporation, except in comparatively few instances, no longer represents a protecting care, a parental influence, over its operatives.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)
“Family life is not a computer program that runs on its own; it needs continual input from everyone.”
—Neil Kurshan (20th century)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
“But, with whatever exception, it is still true that tradition characterizes the preaching of this country; that it comes out of the memory, and not out of the soul; that it aims at what is usual, and not at what is necessary and eternal; that thus historical Christianity destroys the power of preaching, by withdrawing it from the exploration of the moral nature of man; where the sublime is, where are the resources of astonishment and power.”
—Ralph Waldo Emerson (1803–1882)
