Final answer:
With exclusive locking, the operating system prevents other processes from accessing the locked file. The correct answer is C.
Step-by-step explanation:
With exclusive locking, once a process acquires an exclusive lock, the operating system will prevent any other process from accessing the locked file.
The correct answer to the question is 'mandatory.' Mandatory locking prevents other processes from accessing a file exclusively locked by a process, ensuring data integrity.
With mandatory locking, once a process acquires an exclusive lock, the operating system will prevent any other process from accessing the locked file. This is a form of file locking where the operating system enforces locks and ensures that the files being accessed in exclusive mode are not available to other processes until the lock is released. This restriction is used to maintain data integrity.
With exclusive locking, once a process acquires an exclusive lock, the operating system ensures that no other process can access the locked file concurrently. This type of locking mechanism is crucial for scenarios where a process needs to perform operations on a file without interference from other processes. Exclusive locks are commonly employed in situations where data integrity and consistency are paramount.
When a process obtains an exclusive lock on a file, it essentially gains exclusive control over that resource, preventing any other process from reading, writing, or modifying the file until the lock is released. This ensures that the data remains coherent and avoids potential conflicts that might arise if multiple processes were allowed simultaneous access. Exclusive locking is particularly useful in critical applications where the order and timing of file access are essential to prevent data corruption or loss. It provides a level of control that is necessary in scenarios where certain operations must be atomic, meaning they occur without interruption, to maintain the integrity of the shared resource.
