If more than one thread tries to enter inside the critical section at the same time then it might lead to the synchronization problem. Preemption Preemption is the ability of the operating system to preempt(that is stop or pause) a currently scheduled task in favor of a higher priority task...
When one thread performs increment and decrement operations, the other threads must wait for their turn. Organizing threads in such a way is often referred to as thread synchronization. There are several ways to achieve thread synchronization. ...
