1. A
cathode-raY tube and associated electronics connected to a computer' s video output. A monitor ma
Y be either
monochrome (black and white) or colour (
RGB). Colour monitors ma
Y show either digital colour (each of the red, green and blue signals ma
Y be either on or off, giving eight possible colours: black, white, red, green, blue, c
Yan, magenta and
Yellow) or analog colour (red, green and blue signals are continuousl
Y variable allowing an
Y combination to be displa
Yed). 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 t
Ype. The monitor' s variable ma
Y onl
Y be accessed via its access procedures and onl
Y one process ma
Y be activel
Y accessing the monitor at an
Y one time. The access procedures are
critical sections. A monitor ma
Y 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 librar
Y 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 s
Ystem resources to active programs. 6. A program that measures software performance.
