Security Surge protectors and uninterruptible power supplies offer protection from electrical power surges, as you learned in the Protecting Hardware section of this chapter. While these surges are part of everyday life, they are more likely to occur during thunderstorms and peak energy consumption periods. These unavoidable occurrences can damage or ruin sensitive electronic equipment. The processor in a computer is particularly sensitive to the fluctuations in current. When shopping for a surge protector, purchase the best product you can afford. Typically, the amount of protection offered by a surge protector is proportional to its cost. That is, the more expensive the surge protector, the more protection it offers. Research This: Visit an electronics store or view websites with a variety of surge protectors from several manufacturers. Read the packaging or specifications to determine many of the features. Compare at least three surge protectors by creating a table using these headings: manufacturer, model, price, Joule rating (a Joule is the unit of energy the device can absorb before it can be damaged; the higher the Joule rating, the better the protection), warranty, energy-absorption rating, response time, and other features. Which surge protector do you recommend? Why?
