In concurrent programming, concurrent accesses to shared resources can lead to unexpected or erroneous behavior, so parts of the program where the shared resource is accessed need to be protected in ways that avoid the concurrent access. One way to do so is known as a critical section or critical region. … See more Different codes or processes may consist of the same variable or other resources that need to be read or written but whose results depend on the order in which the actions occur. For example, if a variable x is to be read by … See more 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).
