From The Free On-line Dictionary of Computing (18 March 2015) :

  paging
  paged
  
      A technique for increasing the memory space
     available by moving infrequently-used parts of a program's
     working memory from RAM to a secondary storage medium,
     usually hard disk.  The unit of transfer is called a page.
  
     A memory management unit (MMU) monitors accesses to memory
     and splits each address into a page number (the most
     significant bits) and an offset within that page (the lower
     bits).  It then looks up the page number in its page table.
     The page may be marked as paged in or paged out.  If it is
     paged in then the memory access can proceed after translating
     the virtual address to a physical address.  If the
     requested page is paged out then space must be made for it by
     paging out some other page, i.e. copying it to disk.  The
     requested page is then located on the area of the disk
     allocated for "{swap space" and is read back into RAM.  The
     page table is updated to indicate that the page is paged in
     and its physical address recorded.
  
     The MMU also records whether a page has been modified since it
     was last paged in.  If it has not been modified then there is
     no need to copy it back to disk and the space can be reused
     immediately.
  
     Paging allows the total memory requirements of all running
     tasks (possibly just one) to exceed the amount of physical
     memory, whereas swapping simply allows multiple processes
     to run concurrently, so long as each process on its own fits
     within physical memory.
