Lightning strikes on the surface of the earth about 100 times per second. It is estimated that at any given time, 2,000 thunderstorms somewhere on the planet. And the annual losses amount to millions around the world. Lightning can send thousands of volts, coming to a computer via the power cable or phone line. It is rare for lightning to fall directly into a house, but it falls nearby. So the modem or any other part of the computer are often the victims. Sometimes the damage is not perceived immediately, but gradually begin to be felt the effects.

Surge Suppressor. A surge protector, detects the high voltage and off immediately so as not to cause harm. The surge protector should not be confused with the normal current carrying boxes that contain the basics to protect the high level of current, but offer no protection against lightning. Some facts surge suppressors for computers include connections for telephone lines and and care for the modem. Stabilizers. You can also protect your computer using a good surge protector should offer the following features: Internal protection against lightning. Some do not.

Telephone line protection. If you have cable modem, buy one that fits your cable TV and Internet. UPS: uninterruptible power supply. When lightning will strike and cut the power (even for a few seconds), you may lose valuable information from your computer. So if you manage a business, or if important information is used, you may want to invest in a UPS (Uninterruptible Power Supply – uninterruptible power supply). This unit gives the same protection as a stabilizer and have a battery that allows you to save the information when the power goes out unexpectedly. If you buy a UPS, seek the same qualities as a stabilizer, but also takes into account the battery life and software. In conclusion I tell them that all of these protection devices have their limits and to present an electrical storm does not ensure 100% protection, so it would be better to take extra precaution to unplug the computer and disconnect the phone cord when not in use.
