Describe the difference between a monitor and a semaphore
Solution
Monitor: Monitor is a highly structured programming language construct.It consists of Private
variables and private procedures that can only be used within a monitor. Constructors that
initialize the monitor.A number of public monitor procedures that can be invoked by users.
These monitors have no public data.A monitor is a mini OS with monitor procedures as system
calls.
Semaphore: Semaphore is a data structure that is used to provide mutual exclusion to critical
sections. Semaphores mainly support two operations called wait and Signal . The wait operation
blocks a process until the semaphore is open and the signal operation allows another process to
enter.MonitorSemaphoreCondition variables only uses these MonitorsThese can be used in
anywhere but not in Monitorswait() always blocks it\'s callerwait() does not always blocks it\'s
