  • What is the difference between Swapping and Paging?

    Swapping occurs when whole process is transferred to disk,while paging is when some part of process is transferred to disk while rest is still in physical memory. There are two utilities to onitor memory, called vmstat (for bsd, etc),sar( for system V, etc). Page-ins and page-outs are pages
    moved in and out from physical memory to disk, swap-ins and swap-outs are processes moved in and out of disk.
