Fixed priority scheduling is a scheduling discipline, in which tasks queued for utilizing a system resource are assigned a priority each. A task with a high priority is allowed to access a specific system resource before a task with a lower priority is allowed to do the same. A disadvantage of this approach is that tasks assigned with a lower priority may be starved when a large number of high priority tasks are queued. Aging is used to gradually increase the priority of a task, based on its waiting time in the ready queue.<\/p>\n<p>Problem<br \/>\nIn priority-based scheduling algorithms, a major problem is indefinite block, or starvation. A process that is ready to run but waiting for the CPU can be considered blocked. A priority scheduling algorithm can leave some low-priority processes waiting indefinitely. A steady stream of higher-priority processes can prevent a low-priority process from ever getting the CPU.<\/p>\n<p>\u30a8\u30a4\u30b8\u30f3\u30b0\uff08\u30b9\u30b1\u30b8\u30e5\u30fc\u30ea\u30f3\u30b0\uff09<\/p>\n<p>\u30d5\u30ea\u30fc\u767e\u79d1\u4e8b\u5178\u300e\u30a6\u30a3\u30ad\u30da\u30c7\u30a3\u30a2\uff08Wikipedia\uff09\u300f\u3088\u308a<br
