In a nutshell: -Monitor. Enter/exit and mutexes are commonly used for protecting objects From being used by two threads at the same time. Every thread acquires Mutex (resp. enters the monitor) before it uses the object, and no other Thread will be allowed to do the same until the mutex is released (resp. Monitor is exited); the monitor methods are faster and use less memory, Mutexes can be shared using SS Processes -The lock statement internally uses
