Use the following information to help you understand and formulate a plan for lightning protection. When you decide to implement your plan, use the services of a licensed electrician or lightning protection specialist.

If the power goes out, your computer suddenly shuts off, potentially losing whatever data you were working on up to that point, and causing system errors within the Windows environment. What's worse is if a harmful electrical surge comes through the lines and could potentially wipe out your entire computer for good.

A UPS provides electrical power to computers or other devices during a power outage and can be one of the following (TechTarget, 2003):
