单选题 Microsoft's COM is a software{{U}} {{U}} 26 {{/U}} {{/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}} {{U}} 27 {{/U}} {{/U}}standard developed by Microsoft. OLE makes it possible to create{{U}} {{U}} 28 {{/U}} {{/U}}with one application and link or embed them in a second application. Embedded objects retain their original format and{{U}} {{U}} 29 {{/U}} {{/U}}to the application that created them. Support for OLE is built into the Windows and MacOS Operating Systems. A{{U}} {{U}} 30 {{/U}} {{/U}}compound document standard developed mainly by Apple and IBM is called OpenDoc.

【答案解析】[解析] 微软提出的COM是一种软件体系结构，它可以根据二进制软件构件构成应用软件。就像OLE提供的服务一样，COM是组成高层次软件服务的一种基本的体系结构。COM 定义了构件之间进行功能调用的二进制标准，这是使得一个构件能够动态地发现其他构件实现的接口的一种方法，也是标识构件及其接口的特殊机制。 OLE是由微软开发的复合文档标准。OLE可以生成与一种应用有关的对象，并且把它链接或嵌入到另外一个应用中。被嵌入的对象保持原来的格式，而且可以与生成它们的应用链接起来。Windows和MacOS操作系统已经内置了对OLE的支持。主要由Apple和IBM开发的竞争性复合文档标准叫做OpenDoc。
