DEAD LOCK

Deadlock usage refers to situations where multiple processes, threads, or entities are stuck waiting for each other to release resources, causing a standstill, like a traffic jam or database transactions blocked by circular resource requests, while in physical security, a deadlock (deadbolt) is a high-security lock requiring a key for both locking and unlocking external doors for enhanced protection. In computing, deadlocks occur due to circular waits for resources (e.g., File X/Y) and are managed by prevention, avoidance, or detection.
