Microsoft's COM is a software(73) that allows applications to be built from binary software components。

A．structure

B．protocol

C．procedure

D．architecture

Microsoft's COM is a software(146)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(147)standard developed by Microsoft. OLE makes it possible to create(148)with one application and link or embed them in a second application. Embedded objects retain their original format and(149)to the application that created them. Support for OLE is built into the Windows and MacOS Operating Systems. A(150)compound document standard developed mainly by Apple and IBM is called OpenDoc.

ginal API.That is,existing program binaries should continue to operate when run on a system supporting the new API.In addition,existing （72） that are re-compiled and run on a system supporting the new API should continue to operate.Simply put,the API （73） for multicast receivers that specify source filters should not break existing programs.The changes to the API should be as small as possible in order to simplity the task of converting existing （74） receiver applications to use source filters.Applications should be able to detele when the new （75） filter APIs are unavailable(e.g., calls fail with the ENOTSUPP erroe) and react gracefully(e.g., revert to old non-source-filter API or display a meaningful error message to the user).
