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.

“What, then, is the basic difference between todays computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of patterna capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
—Hannah Arendt (19061975)
“See, I have given you authority to tread on snakes and scorpions, and over all the power of the enemy; and nothing will hurt you. Nevertheless, do not rejoice at this, that the spirits submit to you, but rejoice that your names are written in heaven.”
