Two-phase locking: The process in which the locks are acquired during the growing phase and released in a shrinking phase is called two-phase locking. Serializability is the process of processing concurrent transaction which can be achieved through one of the number of different means. One way of achieving serializability is two-phase locking. Using this strategy, locks can be applied on transactions. When one of the locks is released first, no other locks can be applied on that particular transaction. It prevents deadlock which occurs in distributed system.
