The critical section problem
WebCritical Section Problem Critical section is that portion of code in which a process may be changing variables, updating a table, writing a file and so on. For instance, in a given code only a subset of instructions form the critical section. You never modify the shared resource in the entire code. WebTypically, critical sections prevent thread and process migrationbetween processors and the preemptionof processes and threads by interrupts and other processes and threads. Critical sections often allow nesting. Nesting allows multiple critical sections to be entered and exited at little cost.
