推 yupog2003: 第八題得看他先餵MSB還是LSB吧!他說先餵lower line, 02/09 06:39
→ yupog2003: 再來middle,再來high,可是沒說MSB還是LSB先餵@@ 02/09 06:39
→ yupog2003: 從上到下如果是101和011的話,output會變1,也就是5或3 02/09 06:40
→ yupog2003: 從下到上的話就是5或6 02/09 06:41
推 yupog2003: 第九題abc我算都跟你一樣 02/09 06:48
→ yupog2003: 不過c我的想法是先求出transfer rate,一個track 16KB 02/09 06:48
→ yupog2003: 轉一圈需要1/50s,所以transfer rate=16KB/(1/50s)= 02/09 06:48
→ yupog2003: 800KB/s,540KB需要多少ms來傳呢?540KB/800KBps*1000= 02/09 06:49
→ yupog2003: 675ms,加上rotation latency和access time,20ms 02/09 06:49
→ yupog2003: 675ms+20ms=695ms=7 time slices 02/09 06:50
推 yupog2003: 機器語言那題他應該有給appendix? 02/09 06:52
→ yupog2003: 第九題c他有寫:time for moving read/write head 02/09 06:56
→ yupog2003: between the neighboring tracks is negligible 02/09 06:56
→ yupog2003: 所以我猜你的算法應該不行 02/09 06:56
