单选题
Microsoft's COM is a software {{U}}(71) {{/U}} that allows applications to be built from binary software components. COM is the underlying architecture that forms the foundation for higher-level software services, like those provided by OLE. COM defines a binary standard for function calling between components, a way for components to dynamically discover the interfaces implemented by other components, and a mechanism to identify components and their interfaces uniquely.
OLE is a compound {{U}}(72) {{/U}} standard developed by Microsoft. OLE makes it possible to create {{U}}(73) {{/U}} with one application and link or embed them in a second application. Embedded objects retain their original format and {{U}}(74) {{/U}} to the application that created them. Support for OLE is built into the Windows and MacOS Operating Systems. A {{U}}(75) {{/U}} compound document standard developed mainly by Apple and IBM is called OpenDoc.

【正确答案】 B
【答案解析】[参考译文] 微软提出的COM是一种软件体系结构 (architectur)，它可以根据二进制软组件构成应用软件。COM定义了组件之间进行功能调用的二进制标准，这是使得一个组件能够动态地发现其他组件实现的接口的一种方法，也是标识组件及其接口的特殊机制。 OLE是由微软开发的组合文档(document)标准。OLE可以生成与一种应用有关的对象(objects)，并且把它链接或嵌入到另外一个应用中。被嵌入的对象保持了原来的格式，而且可以与生成它们的应用链接(links)起来。对OLE的支持已经内置在Windows和MacOS操作系统中。主要由Apple和IBM开发的竞争性(competing)组合文档标准称为OpenDoc。
