Just my 2 cents, but hotplugging is when you have a device that you unplug
from the machine... Such as the ethernet card itself, or a printer, etc,
that is recognized as being unplugged/replugged in. :) For example,
PC-Cards/Cardbus/PCMCIA cards in laptops are an example of a hotplugging
card... Say you need a network card, so you just plug in the network card,
and the operating system recognizes it and loads the appropriate drivers,
then when you don't need it and unplug it, the OS recognizes that the driver
is no longer necessary and unloads it... At least that's my take on it. ;)
The term also applies to harddrives, etc, which can be hot-pluggable and
hot-swappable.
