Does anyone understand what are the mechanics behind the ISO

Yes, I understand them. At least for the Canon 1D Mark II: there
are three buttons, a finger wheel, and a thumb wheel. Maybe the
Nikon D70s has the Telepathic Adaptor which can lock onto the mind
of the photographer, thus dispensing with these crude mechanical
implements?
I think the poster was asking a more generalized question than you
responded to, but hey, who am I to stop you from making a jerk of
yourself.
Usually the lowest ISO setting of your digital camera is going to be
where you get the best picture with the lowest noise. Higher
settings
are amplified, I believe, so noise is increased.
They are only in increments of 100, 200, 400 to remain reciprocal
with
shutter speed and aperture settings.
I think the OP was asking how changing the ISO setting affects how the
camera responds to a light stream striking the sensor when the camera
is set to record raw images.
I don't know.
