Description: On exit refers to the actions taken when a process finishes its execution in an operating system. This term is fundamental in the context of process management, where every time a program or application closes, the operating system must perform a series of tasks to free resources and ensure system stability. These actions may include releasing memory, closing open files, and notifying other processes about the termination. Proper management of these actions is crucial to avoid memory leaks and other issues that can affect system performance. Additionally, handling exit events may include executing specific scripts or commands that the user or system administrator has configured, allowing for the customization of system behavior when closing applications. In summary, ‘on exit’ encapsulates a set of procedures that ensure the termination of a process is handled efficiently and orderly, contributing to the overall health of the computing environment.
