WebSemaphores in Operating System. Semaphores are two-field data types, one of which is a non-negative type of integer S.V and the other is a set of processes in a queue S.L. It is used to address critical section problems by using two atomic operations, wait and signal, to synchronize processes in this. In this article, we will look more into the ...

A critical section will usually terminate in finite time, and a thread, task, or process will have to wait for a fixed time to enter it (bounded waiting). To ensure exclusive use of critical sections some synchronization mechanism is required at the entry and exit of the program.
