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.
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.
