1. A
cathode-ray tube and associated electronics connected to a computer' s video output. A mon
ITor may be e
ITher
monochrome (black and wh
ITe) or colour (
RGB). Colour mon
ITors may show e
ITher dig
ITal colour (each of the red, green and blue signals may be e
ITher on or off, giving eight possible colours: black, wh
ITe, red, green, blue, cyan, magenta and yellow) or analog colour (red, green and blue signals are continuously variable allowing any combination to be displayed). Dig
ITal mon
ITors are sometimes known as
TTL because the voltages on the red, green and blue inputs are compatible w
ITh TTL logic chips. See also
gamut,
multisync,
visual display unIT. 2. A programming language construct which encapsulates variables, access procedures and in
ITialisation code w
IThin an abstract data type. The mon
ITor' s variable may only be accessed via
ITs access procedures and only one process may be actively accessing the mon
ITor at any one time. The access procedures are
crITical sections. A mon
ITor may have a queue of processes which are wa
ITing to access
IT. 3. A hardware device that measures electrical events such as pulses or voltage levels in a dig
ITal computer. 4. To oversee a program during execution. For example, the mon
ITor 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 pos
ITion and how often each profiled function was called.

ITor(3). 5. A control program w
IThin the
operating system that manages the allocation of system resources to active programs. 6. A program that measures software performance.
