※ 引述《yesa315 (XD)》之銘言： : 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) : 答案寫A 但我覺得是C : hardware interrupt可以是I/O complete之類 : 感覺clock interrupt比較正確 : 有人這麼認為嗎? 謝謝我覺得答案是 (E) X: 當timer interrup(clock interrupt)發生時，"running" state → "ready" state Y: 當I/O request、event wait或是SVC(software interrupt)， "running" state → "waiting" state 有錯誤請多指教，謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.134.129.184
