Resume

Microsoft has set up the OLE technology ("Object Linking and Embedding") in order to allow some applications to communicate objects and services with other applications. For that, Microsoft established standards of communication COM (Component Object Model"), then DCOM ("Distributed COM") which establish the rules of communication between the applications of a same machine or on a network. The functionalities of the components are gathered in interfaces, it is then a game of function which makes it possible to use a component. Some types of bond exist between the application and the object, in fact either you "copy-paste" the object of an application to another, or you can create a link between the object and the application, it is then an OLE connection.
