  Read-Only Memory
  ROM
  
      (ROM) A type of data storage device which is
     manufactured with fixed contents.  In its most general sense,
     the term might be used for any storage system whose contents
     cannot be altered, such as a gramophone record or a printed
     book; however, the term is most often applied to
     semiconductor integrated circuit memories, of which there
     are several types, and CD-ROM.
  
     ROM is inherently non-volatile storage - it retains its
     contents even when the power is switched off, in contrast to
     RAM.
  
     ROM is often used to hold programs for embedded systems
     since these usually have a fixed purpose.  ROM is also used
     for storage of the lowest level bootstrap software
     (firmware) in a computer.
  
     See also Programmable Read-Only Memory.
