Answer Posted / suchitra
actually the layers are
outermost layer is user
inner layer is kernel
and inner most layer is hardware.
so when user sends any command it willnot go directly to
hardware.first it will go and ask permission from kernel
and if kernel permits then the command will reach hardware.
so unlike in other operating system the user cannot
directly interact with hardware
