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.
