Re: [理工] [OS]-Process

[cansister (cansister)]

※ 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

→ yesa315:囧 我打錯 我也認為是E 一時沒注意到
推 tryPTT:我覺得AE都對耶..因為time out(clock)、硬體中斷(hardware)
→ tryPTT:都會造成state從running→ready..   有錯請指正
推 tryPTT:剛又想想..也許clock他歸在硬體.... (純屬猜測..)
推 yesa315:假如他歸類在硬體 又何必寫出clock這答案? 這是單選題..
推 tzuci6649:不論答案是什麼，我都笑了。 單選題不是只有一個答案..
