Power surge
An unexpected increase in the amount of electrical voltage in an electrical line. A power surge can provide too much power to a computer or electrical device generally causing damage to that device making the device not operate at all or improperly. Users can help prevent power surges with surge protectors.

You already got some good definitions from those who answered. But if you are interested in protection of your computer system, the best method is not surge protectors but in-line (not stand-by) UPS (Universal Power Supplies).
Surge protectors, like condoms, are good for one use only. It will protect you the first time. The same surge protector will not protect you a second time (there are some that would, but you constantly have to monitor it, and reset a switch after each protection).
An in-line UPS uses current directly from a battery that is constantly being recharged from the power outlet. The battery absorbs the surge. There is nothing to reset or change. Besides, it also protects you from brownouts (not enough voltage) and blackouts (no voltage at all)

A power surge is a sudden, short, temporary increase in voltage, which may be hazardous to your computer's well being.
The best way to protect against them is to have a well made surge protector which will shunt the surge to ground, and protect your electronic gear.
