WitrynaSwap space is divided into blocks the same size as memory pages (usually 4kB), and a record of the mapping of these pages to application memory forms an extension of the virtual memory subsystem in the CPU and OS. That is, there is already a mapping system between application memory spaces and the actual physical memory address.
