1. Monitor is one of the concurrency mechanisms. It is usually a piece of (A) software (B)
hardware (C) firmware (D) may be either of the above (E) None of the above
Solution
Monitors are abstract data types (or later, objects) with special support for concurrent
programming, designed to solve the problems like forgetting to take a lock (or taking the wrong
lock) and forgetting to release a lock
It is an instance of a class that which can be used safely by many threads. Mutual exclusion is
used to execute all the methods of a monitor. This policy makes easier to work with monitor and
to develop the method content of the monitor.
Answer :
(E) None of the above
