Explanation:

Oracle's default locking mechanisms lock data at the lowest level of restrictiveness to guarantee data integrity while allowing the highest degree of data concurrency. Data locks protect data. For example, table locks lock entire tables, row locks lock selected rows. Dictionary locks protect the structure of objects.
