Can somebody please explain to me in (layman's terms!!) how to find out
if a microprocessor is an i386, i486, i586, i686, i786 etc. etc?

I am not interested in knowing the difference from an
engineering/computer science standpoint.  That would be way over my
head!  Given that I know what microprocessor I have installed (brand,
model, MHz), I just want to know if it is an i386, i486 etc.

I keep on hitting this problem when I want to download things like
Parted Magic or some Linux distributions...
