Locking

Locking in computing refers to a mechanism that prevents multiple programs or users from changing the same data simultaneously, which could cause conflicts or data corruption. When a process locks a piece of data, it ensures exclusive access—no other process can modify it until the lock is released. This maintains data integrity and consistency, especially in multi-user or multi-process environments. Locks can be temporary (during a specific operation) or longer-term, depending on the system’s needs. Essentially, locking acts as a controlled safeguard to coordinate access and maintain reliable data management.
