In addition to this, paging introduces the benefit of page-level protection. In this system, user-level processes can only see and modify data which is paged in to their own address space, providing hardware isolation. System pages are also protected from user processes. On the x86-64 architecture, page-level protection now completely supercedes [[Segmentation]] as the memory protection mechanism. On the IA32 architecture, both paging and segmentation exist, but segmentation is now considered 'legacy'.
