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.
