That is, system architecture is concerned with a total system, includinghardware. software, and humans.Softwarearchitectural structures can be divided into three major categories, dependingon the broad nature of the elements they show.1）（73）embodydecisions as a set of code or data units that have to be constructed orprocured.2）（74）embody decisions as to how the systemis to be structured as set of elements that have runtime behavior. andinteractions.3）（75）embody decisions as to how thesystem will relate to nonsoftware structures in itsenvironment(suchas CPUs, file systems, networks, development teams, etc.).71.( )A.attributesB.constraintC.functionalityD.requirements
The API changes should provide both source and binary （71） for programs written to the original 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).71.A.capabilityB.compatibilityC.labialityD.reliability
