Homonym: locking (Lock)
Locking is a technique used in various fields, including computer science and engineering, to control access to shared resources. It ensures that only one process or user can access a resource at a time, preventing conflicts and maintaining data integrity. For example, in a database, locking can prevent multiple users from modifying the same record simultaneously.
In the context of security, locking refers to mechanisms that secure doors, safes, or other entry points. Physical locks, such as padlocks or deadbolts, restrict access to authorized individuals. Similarly, digital locks, like passwords or encryption, protect sensitive information from unauthorized access.
