单项选择题
MIMD systems can be classified into (71) -oriented systems, high-availability systems and response-oriented systems. The goal of (71) . oriented multiprocessing is to obtain high (71) (72) minimal computing cost. The techniques employed by multiprocessor operating systems to achieve this goal take advantage of an inherent processing versus input/output balance in the workload to produce (73) and (74) loading of system (75) .
（75）处填（）。
A．resource
B．resources
C．source
D．sources
答案
参考答案：B
解析：
(参考译文)MIMD系统可以分成面向吞吐量(throughout)的系统、高实用性的系统和面向响应的系统。其中面向吞吐量的系统的目标是以最低的计算代价获得高吞吐量。多处理系统为达到这一目标，而利用其固有的对工作量中I/O平衡的处理，来达到对系统资源(re-source)负载的平衡(balanced)和均可(uniform)。
