VM Table use
  Given a memory access, its address is parsed into
    Virtual memory page table pointer.

    Offset into the memory page.

  (Our example) Top 10 bits of an @ point to the table entry (slot).

  The table entry lists the 6 bit frame id of a real memory frame.
    
  Lower 14 bits are concatinated to the 6 bit frame id from table to find 
    the real memory @ of interest.

  If entry shows that virtual page not in physical frame
    Page fault occurs
    
    If all frames filled
      A particular page frame is chosen.
      If dirty bit set
        Existing frame written out onto secondary storage before purging.

    Needed virtual page will be fetched.
