What will happen if interruption occurs at a critical section?

If an interruption occurs at a critical section, it can lead to race conditions or inconsistencies in data since multiple processes may attempt to access or modify shared resources simultaneously. This can compromise the integrity of the system and produce unpredictable results. To prevent such issues, synchronization mechanisms like mutexes or semaphores are typically used to ensure that only one process can access the critical section at a time. Proper handling of interruptions is crucial to maintaining system stability and data consistency.
