data object

For COM. Used for data transfer between MMC and snap-ins and between multiple snap-ins. A data object is an instance of a class that implements the IDataObject interface. MMC requests data objects from snap-ins that insert scope or result items by calling the IComponentData::QueryDataObject or IComponent::QueryDataObject method.

dynamic-link library (DLL)

Modules that contains functions and data that can be loaded at runtime by a calling module (an executable file or another DLL). When a DLL is loaded, it is mapped into the address space of the calling process (module). The calling module can call the exported functions of the DLL to make use of the functionality provided by the DLL.

Snap-ins are implemented as in-process server DLLs that run in the process space of an instance of MMC.
