WebMar 24, 2024 · The critical section is a part of the program code, where we want to avoid concurrent access. We can use a binary semaphore to solve the critical section problem. In this case, the semaphore’s initial value is 1 in the kernel: In the above example, we guarantee mutual exclusion in critical section access. WebDec 13, 2024 · Mutual exclusion is a property of process synchronization which states that “no two processes can exist in the critical section at any given point of time”.

The solution implies that before entering into the critical section the process must acquire a lock and must release the lock when it exits its critical section. Using of lock also prevent the race condition.

WebExit Condition: Every critical section must end with an exit condition which alerts the system regarding the exit.
