RFI

Radio Frequency Interference (RFI) is our second demon, and like its evil brother, EMI, can be a real challenge to track down.

On occasion, for example a PC near a radio or television station transmitter can be overwhelmed by the sheer amount of energy.

The only solution in this type of situation is to make a Faraday shield. This is a metal shield that is attached to ground.

Corrupt, Not Destroy

EMI and RFI can corrupt data, but cannot destroy computer equipment.


[spacer]Really Intense EMI

Actually, intense RFI can completely fry a computer. This is known as an Electro Magnetic Pulse (EMP). While the most famous method of generating EMP is with a nuclear explosion, the web site security portal .com points out EMP could be created by chemical means. Currently the site suggests this is a low risk threat.


Our last demon is the easiest to corral, and the most fatal to equipment if it is not addressed.
