Locking is a technique that is used to resolve the lost-update problem. When a transaction accesses a piece of data, it acquires a lock on that data to prevent other transactions from modifying it. This ensures that only one transaction can modify the data at a time, which eliminates the possibility of lost updates. Preemptive updating involves updating the database immediately after each transaction, which can be inefficient. Sharing, task switching, and multitasking are not directly related to resolving the lost-update problem.
