1. A
cathode-ray tube and associated electronics connected to a computer' s video output. A monit
OR may be either
monochrome (black and white)
OR colour (
RGB). Colour monit
ORs 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 monit
ORs 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 monit
OR' s variable may only be accessed via its access procedures and only one process may be actively accessing the monit
OR at any one time. The access procedures are
critical sections. A monit
OR 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. F
OR example, the monit
OR 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.

OR(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 perf
ORmance.
