From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  overhead
       
          1. Resources (in computing usually processing time or storage
          space) consumed for purposes which are incidental to, but
          necessary to, the main one.  Overheads are usually
          quantifiable "costs" of some kind.
       
          Examples: The overheads in running a business include the cost
          of heating the building.  Keeping a program running all the
          time eliminates the overhead of loading and initialising it
          for each transaction.  Turning a {subroutine} into {inline}
          code eliminates the call and return time overhead for each
          execution but introduces space overheads.
       
          2.  information, such as control, routing, and
          error checking characters, that is transmitted along with the
          user data.  It also includes information such as network
          status or operational instructions, network routing
          information, and retransmissions of user data received in
          error.
       
          3. Overhead transparencies or "slides" (usually 8-1/2" x 11")
          that are projected to an audience via an overhead (flatbed)
          projector.
