( ) 3.Which of the following is not the way that CPU communicates with I/O?
(1) Direct memory access (2) Pipelining (3) Interrupt (4) Programmed I/O
答:(1)直接记忆体存取,是I/O跟记忆体沟通的方法。跟CPU有关?
(2)管线,是机器提高工作量的方法。允许机器各步骤在管线重叠。这跟I/O有关?
(3)中断,是分时系统工作单元停止的讯号。这跟I/O有关?
(4)我只知道mapped I/O 。programmed I/O就不晓得了。不过看起来是。
所以,以上只有一个是? 可是题目是问 not 耶...
( ) 6.If an system architecture has 64-bit addresses, how many registers
it will have?
(1) 64 (2) 6 (3) 2^64 (4) 32 (5) unknow
完全不会...没学过的感觉,an overview里有这观念吗?
( ) 7.Which programming language paradigm do FORTRAN,C,Pascal,Ada,and C++
belong to ?
(1) object-oriented (2)logic (3)functional (4)imperative (5) none of above
答:C++是物件,其他都是命令式。 所以?该选5吗?
( ) 9.add the following nodes to a binary search tree in the order they appear
6 34 17 19 16 10 23 3 What is the output of a postorder traversal of
this tree?
(1) 3 10 16 23 19 17 34 6 (2) 3 6 17 16 10 19 23
(3) 6 3 34 17 16 10 19 23 (4) 10 16 23 19 17 34 3 6
答:前序是从小到大。後序是从大到小。都没这种答案,所以是中序?
中序是节点、左、右。所以是3罗? postorder是中序的英文?
我的字典查不到这个字,只有看到post是後的字根~
简答题:
13.Explain the following terms;
(a) Multiprocessor
(b) MIPS (Million Instructions Per Second)
(c) Benchmark
(a)知道是多处理器有多个CPU,然後还要解释什麽吗?
(b)跟(c)则完全没看过...

1F:推 dichia:9.ans:(1) postorder是後序 有错误请指正 210.85.132.240 06/13
2F:推 dynamicy:第十题应该是2吧..insertback..deletefrom 218.170.45.182 06/15
3F:推 dynamicy:另外,第一题我觉得怪怪的,不是只有负数才有捕数 218.170.45.182 06/15
