Paging: Introduction
pages.cs.wisc.eduOne of the most important data structures in the memory management subsystem of a modern OS is the page table. In general, a page table stores virtual-to-physical address translations, thus letting the system know where each page of an address space actually resides in physical memory. Because each address space requires such translations, in gen-
