参考答案和解析

正确答案：D
解析：软件设计是一个创造性的过程，它需要大量设计者的才能。设计从书本里是学不到的，它必须通过实践，从经验中学习，并且对现有的系统研究才能掌握。一个设计很好的软件系统易于实现、易于维护，而且容易理解和可靠性强。设计不佳的软件系统，尽管他们可能维护代价昂贵，但是却难以测试，并且可靠性差。

第3题：

Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers ___71___ through a real-time communication network such as the Internet. In science, cloud computing is a ___72___ for distributed computing over a network, and means the ___73___ to run a program or application on many connected computers at the same time.
The architecture of a cloud is developed at three layers: infrastructure, platform, and application. The infrastucture layer is built with virtualized computestorageand network resources. The platform lay-er is for general-purpose and repeated usage of the collection of software resources. The application layer is formed with a collection of all needed software modules for SaaS applications. The infrastucture layer serves as the ___74___ for building the platform layer of the cloud. In turn, the platform layer is founda-tion for implementing the __请作答此空___ layer for SaaS application.

A.resource
B.service
C.application
D.software

答案：C
解析：
云计算是一个用来描述各种计算概念的一个短语，计算概念涉及大量计算机通过实时通信的网络，如Internet，连接在一起。在科学研究中，云计算是分布式网络计算的同义词，意味着有能力同时在多台互连的计算机上运行一个程序或应用。
云的结构分为3层：基础设施、平台和应用。基础实施层由虚拟计算机存储和网络资源构成；平台层是具有通用性和复用性的软件资源的集合；应用层是云上针对SaaS应用的所有应用软件的集合。基础设施层时建立平台层的硬件基础；相应地，平台层是执行应用层SaaS应用的基础。
