Priority inheritance is a term used in real-time computing and operating systems to ensure that a high-priority task is executed before lower-priority tasks. This technique is crucial for ensuring the smooth functioning of critical systems. Some synonyms for Priority inheritance include priority ceiling, priority donation, and priority inheritance protocol. Priority ceiling is similar to priority inheritance, but instead of a high-priority task inheriting the priorities of lower-priority tasks, it sets a priority ceiling that prohibits lower-priority tasks from accessing system resources while the high-priority task is running. Priority donation is a more advanced form of priority inheritance that allows lower-priority tasks to donate their resources to higher-priority tasks, enabling critical tasks to run without interruption.
