  volatile storage
      (NVS, persistent storage, memory) A term describing
     a storage device whose contents are preserved when its power
     is off.  Storage using magnetic media (e.g. magnetic disks,
     magnetic tape or bubble memory) is normally non-volatile
     semiconductor+memories+({static+RAM">by nature whereas semiconductor memories ({static RAM and
     especially dynamic RAM) are normally volatile but can be
     made into non-volatile storage by having a (rechargable)
     battery permanently connected.
     Dynamic RAM is particularly volatile since it looses its
     data, even if the power is still on, unless it is refreshed.
     An acoustic delay line is a (very old) example of a volatile
     storage device.
     Other examples of non-volatile storage are EEPROM, CD-ROM,
     paper tape and punched cards.
