1. com, the component object model, is a standard on how to build components and how to build applications through components.2. Advantages of components: applications can develop and change over time, custom applications, Component Libraries, and distributed components.3. Requirements for components: components must be dynamically connected; internal implementation details must be hidden.4. the
COM (formerly known as OLE) represents Microsoft's "Component Object Model" (Component object models), which is the basis for all ActiveX technologies, including ActiveX controls, automation, and ActiveX documents. But COM also contains more stuff. It is a special specification that the component objects that it develops can be "interoperable" through the specialized features of the operating system. In pra

People familiar with object-oriented programming and network programming must be familiar with ActiveX, Ole, and COM/DCOM concepts, but the relationship between them is still vague to many.
The difference between components and objects should be clarified first.
A component is a reusable module that consists of a set of processing

Com is sometimes referenced as common object model but Microsoft officially callit Component Object Model. microsoft also developed DCOM as an extension of COM. DCOM was designed with Distributed Computing in perspective. CORBA stands for Common Object Request Broker Architecture and developed by Object Management Group (OMG ).
