preemptive scheduling 和 time slicing?

preemptive scheduling, 優(yōu)先級別最高的任務(wù)會被執(zhí)行, 除非它進入等待狀態(tài)或者死了或者一個更高優(yōu)先權(quán)的任務(wù)進來.

time slicing, a task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and other factors.
