Is it possible to have "32 bit operating system" running on "64 bit processor" ?
What happens when I target my runtime in .net to x-64 and my OS is 32 bit ?
One more to add "by the way what is meant by 32 bit OS (vs 32 bit processor)" ?
回答1:
Yes; the x64 processor is just an extension of x86, which is a 32-bit processor.
It will not run.
It means the OS contains code for running on a 32-bit processor.
