X could lead a process to leave from the "running" state to the "ready" state and Y could lead a process to leave from the "running" state to the "waiting" state . What is (X,Y)? (A)(hardware interrupt,software interrupt) (B)(hardware interrupt,clock interrupt) (C)(software interrupt,clock interrupt) (D)(clock interrupt,hardware interrupt) (E)(clock interrupt,software interrupt) 答案写A 但我觉得是 E hardware interrupt可以是I/O complete之类 感觉clock interrupt比较正确 有人这麽认为吗? 谢谢 --
