exception
     
        An error condition that changes the normal {flow of control}
        in a program.  An exception may be generated ("raised") by
        {hardware} or {software}.  Hardware exceptions include
        {reset}, {interrupt} or a signal from a {memory management
        unit}.  Exceptions may be generated by the {arithmetic logic
        unit} or {floating-point unit} for numerical errors such as
        divide by zero, {overflow} or {underflow} or {instruction
        decoding} errors such as privileged, reserved, {trap} or
        undefined instructions.  Software exceptions are even more
        varied and the term could be applied to any kind of error
        checking which alters the normal behaviour of the program.
