Master-Slave System Definition/Meaning:
A system that has more than one processor and in which one
of the processors is designated as being the master and all other processors are
slaves. The master processor is capable of actions that the slaves cannot
perform, usually in connection with resource scheduling and the initiation of
peripheral transfers. This approach means that the problems of synchronization
are greatly reduced, since only the master processor can be active in what might
otherwise be critical regions. It has the drawbacks of introducing an
artificial asymmetry between processors, and of causing delays when processes
that might be able to proceed are in fact delayed since the only available
processors do not have the necessary privileges.
