monitor
     
        1. A {cathode-ray tube} and associated electronics connected
        to a computer's video output.  A monitor may be either
        {monochrome} (black and white) or colour ({RGB}).  Colour
        monitors may show either digital colour (each of the red,
        green and blue signals may be either on or off, giving eight
        possible colours: black, white, red, green, blue, cyan,
        magenta and yellow) or analog colour (red, green and blue
        signals are continuously variable allowing any combination to
        be displayed).  Digital monitors are sometimes known as {TTL}
        because the voltages on the red, green and blue inputs are
        compatible with TTL logic chips.
     
        See also {gamut}, {multisync}, {visual display unit}.
     
        2. A programming language construct which encapsulates
        variables, access procedures and initialisation code within an
        abstract data type.  The monitor's variable may only be
        accessed via its access procedures and only one process may be
        actively accessing the monitor at any one time.  The access
        procedures are {critical section}s.  A monitor may have a
        queue of processes which are waiting to access it.
     
        3. A hardware device that measures electrical events such as
        pulses or voltage levels in a digital computer.
     
        4. To oversee a program during execution.  For example, the
        monitor function in the {Unix} {C} library enables profiling
        of a certain range of code addresses.  A histogram is produced
        showing how often the {program counter} was found to be at
        each position and how often each profiled function was called.
     
        {Unix} {man} page: monitor(3).
     
        5. A control program within the {operating system} that
        manages the allocation of system resources to active
        programs.
     
        6. A program that measures software performance.
