A surge protector is a piece of hardware that your computer is plugged into. The protector then plugs into the wall. Thus, it is an intermediary between your computer and the power outlet. The surge protector prevents dangerous levels of power from reaching your computer and causing overload problems.
Here's the scenario:
You're using your computer during an electrical storm. Lightning strikes and sends a high amount of power to your computer.
With a surge protector, the surge protector notices the power is too high and prevents the high power from reaching your computer.
Without a surge protector, the high voltage travels right to your machine, and you're left to pray that it doesn't overload your computer and cost you to have repairs performed.
A surge protector can also prevent spikes that occur should the power go out and then come back on at a higher level.
Thus, surge protectors are relatively cheap and are the standard in computer protection. A wise investment to be sure.
