From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  paging
       
           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 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}.
