Re: [理工] [OS] 交大100
題目太長了，請看圖片
答案CDE
14題
alloc max need 系統原有
A B C A B C A B C A B C
p0 0 1 0 7 5 3 6 4 3 10 5 7
1 2 0 0 3 2 2 1 2 2 alloc後剩
2 3 0 2 9 0 2 6 0 0 3 3 2
3 2 1 1 2 2 2 0 1 1
4 0 0 2 4 3 3 4 3 1
if p1 request additional A = 1 , C = 2
此時系統剩下 A2 B3 C0
但是P3需要0 1 1 為什麼CD可以選
B選項 分配 0 2 0 給P0 系統剩下 2 1 0 < 所有的need
為什麼B沒有呢
