Quizplus · Accepted Answer

Locking is one of the methods used to prevent concurrent access to data and ensure consistency in the updates made by multiple users. Locking allows only one user at a time to access a data item or a set of related data items, thus preventing the lost-update problem where two users overwrite each other's changes. Therefore, the statement "Locking must be used to coordinate the activities of users to prevent the lost-update problem" is true.
