问题 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.
