Question 6 When only paging is implemented for memory management, why do we end up with a two-sta machine? Pages allow programmers to designate different memory areas at various levels of sensitivity Pages have no logical unity and only rely on the kernel and user mode separation x86 hardware only supports segmentation The page translation table can only handle a single state machine
