单选题 For each blank, choose the best answer from the four choices and write down on the answer sheet.
It is claimed that Al applications have moved from laboratories to the real world. However, conventional von Neumann computers are{{U}} {{U}} 50 {{/U}} {{/U}}for Al applications, because they are de- signed mainly for numerical processing. In a larger yon Neumann computer, there is a larger ratio of memory to processing power and consequently it is even less efficient. This{{U}} {{U}} 51 {{/U}} {{/U}}remains no matter how fast we make the processor because the length of the computation becomes dominated by the time required to move data between{{U}} {{U}} 52 {{/U}} {{/U}}and memory. This is called the yon Neumann{{U}} {{U}} 53 {{/U}} {{/U}}. The bigger we build the machines, the worse it gets. The way to solve the problem is to diverse from the traditional architectures and to design special ones for Al applications. In the research of future Al architectures, we can take advantages of many{{U}} {{U}} 54 {{/U}} {{/U}}or currently emerging concepts. in computer architecture, such as dataflow computation, stack machines, tagging, pipelining, systolic array, multiprocessing, distributed processing, database machines, and inference machines.

  • B. question
  • C. way
  • D. bottleneck
【正确答案】 D
【答案解析】[解析] 本题的考查要点是计算机英语。 [解析] 此处只有D选项意思最符合题意。是指瓶颈问题。
单选题
  • A. existing
  • B. new
  • C. used
  • D.old-fashioned
【正确答案】 A
【答案解析】[解析] 本题的考查要点是计算机英语。 [解析] 这里指现存的与下文的出现的相对应,所以只能选A。
单选题 在Linux系统中,一般用{{U}} {{U}} {{/U}} {{/U}}命令来测试另一台主机是否可达。
  • A.ping
  • B.ifconfig
  • C.netstat
  • D.uname
【正确答案】 A
【答案解析】[解析] 本题考查网络相关的命令。其中,ping的目的是为了测试另一台主机是否可达; ifconfig命令一般在引导时运行,以配置主机上的每个接口;netstat命令提供系统上的接口信息;uname打印系统信息。
