No Michael, that is not exactly correct. All parts of a computer are
vulnerable to an EMP if it is very strong. Having a cable plugged into
it (which acts as an antenna) makes it much more vulnerable. Having a
phone line plugged in can be even more vulnerable if the the cable does
not have have twisted pairs but instead has straight wire.
When it comes to radio frequencies, resonance is the key. To shed some
light on this for yourself, try studying for a Ham Radio license. You
can start with hamwhisperer.com. That one is free.

ohhhhhh.... so the ethernet PORTS are vulnerable, regardless of if s
cable is attached to it. I think you mean it this way because there is
no cable attached to the ethernet portOtherwise the instructions don't
make sense.

I explained that earlier. ethernet ports are vulnerable. Wires
pick up from the air radio pulses generated by lightning and power
surges.
This turns into voltage in the ethernet cable. Not frequent but it
can happen.
Also, only a proper ups, not a surge protector, can protect you from a
brownout.
make sure you run your network cable, and your broadband cable
(coax) through a UPS for best protection. (as well as the AC plugs!)

here is a question... if I had a power surge why was only 1
computer`affected of the 4 in my house. one other rhing it is
the only
one connected to the internet wirelessly.

On the multimeter thing - if you happen to get a coupon
for a free
multimeter from Harbor Freight that's your cheapest
possible
meter, and
according to a friend its not a bad meter.
If you want to buy it I think its under $10, but I'm
not sure. In
addition, Lowes, Home Depot, Radio Shack, Fry's, and that
computer store
on Country Club near Main in Mesa all should have meters as
well. As
well as all your online options and whatever other
local attractions
I've forgotten ... oh, I bet 'the candy store' (Ham Radio
Outlet) has
meters too. ;-)
And a meter that works is generally handy for all sorts
of things
anyway, so at least one meter is highly recommended...
