The implementation of critical sections vary among different operating systems. 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.
