 for firmware
From WordNet (r) 3.0 (2006) :

  firmware
      n 1: (computer science) coded instructions that are stored
           permanently in read-only memory [syn: firmware,
           microcode]

From The Jargon File (version 4.4.7, 29 Dec 2003) :

  firmware
   /ferm'weir/, n.
  
      Embedded software contained in EPROM or flash memory. It isn't quite
      hardware, but at least doesn't have to be loaded from a disk like regular
      software. Hacker usage differs from straight techspeak in that hackers
      don't normally apply it to stuff that you can't possibly get at, such as
      the program that runs a pocket calculator. Instead, it implies that the
      firmware could be changed, even if doing so would mean opening a box and
      plugging in a new chip. A computer's BIOS is the classic example, although
      nowadays there is firmware in disk controllers, modems, video cards and
      even CD-ROM drives.
  

From The Free On-line Dictionary of Computing (18 March 2015) :

  Firmware
  
     Software stored in read-only memory (ROM) or programmable ROM
     (PROM).  Easier to change than hardware but harder than
     software stored on disk.  Firmware is often responsible for
     the behaviour of a system when it is first switched on.  A
     typical example would be a "monitor" program in a
     microcomputer which loads the full operating system from disk
     or from a network and then passes control to it.
