Paging: Introduction
One 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-

When would it make sense not to use a database system? Answer 1.1 A database is an integrated collection of data, usually so large that it has to be stored on secondary storage devices such as disks or tapes.
