| | Component Object Model - Wikipedia, the free encyclopedia |
 | | COM objects may be instantiated and referenced from within a process, across process boundaries within a computer, and across a network, using the DCOM technology. | | | COM objects use a technique called reference counting to ensure that object is properly disposed of when all code that uses the object has finished. | | | COM was the major software development platform for Windows and, as such, influenced development of a number of supporting technologies. |

| | OLE Component Object Model |
| | Object references (pointers) in Windows Objects are not references to the object itself, as in C++, but rather are pointers to one of the object's interfaces. | | | Objects may only be accessed through the operations defined in one of the object's interfaces. | | | In the Component Object Model, inheritance is simply considered as a language-specific tool (e.g., in C++) that may be useful for implementing classes and defining interfaces in that language. |

| | Component Object Model Specification, Part I: Component Object M... |
| | COM supports distributed objects; that is, it allows application developers to split a single application into a number of different component objects, each of which can run on a different computer. | | | COM is designed to allow clients to transparently communicate with objects regardless of where those objects are running, be it the same process, the same machine, or a different machine. | | | Component Object Model enables software suppliers to package their functions into reusable software components in a fashion similar to the integrated circuit. |

| | Distributed component object model - Wikipedia, the free encyclopedia |
| | Distributed Component Object Model (DCOM) is a Microsoft proprietary technology for software components distributed across several networked computers to communicate with each other. | | | Ironically, however, the difficulties involved in getting either of these technologies to work over Internet firewalls, and on unknown and insecure machines, meant that normal HTTP requests in combination with web browsers won out over both of them. | | | In terms of the extensions it added to COM, DCOM had to solve the problems of |

| | COM (Component Object Model) (Linktionary term) |
| | COM (Component Object Model) is a Microsoft specification that defines the interaction between components in the Windows environment. | | | COM was introduced in 1993, and its first major implementation was in Windows 95, although it is the basis of OLE (Object Linking and Embedding), which is an object-based service that allows applications running in the same computer to interact and share information. | | | DCOM (Distributed Component Object Model) is the network version of COM that allows objects running in different computers attached to a network to interact. |

| | Component Object Model |
| | COM helps to access components loaded in different machines on the network - COM component can reside anywhere on our computer or even on another computer connected to a network. | | | COM promotes Object-oriented programming (OOP) - The primary characteristics of OOP are encapsulation, which allows the implementation details of an object to be hidden, polymorphism, which is the ability to exhibit multiple behaviors, and inheritance, which allows for the reuse of existing classes in order to design new and more specialized classes. | | | COM promotes component-based software development - before component-based development came, software programs have been coded using procedural programming paradigm, which supports linear form of program execution. |

| | Component Object Model (COM) |
| | COM specifies a binary standard for interfaces to ensure dynamic interoperability of binary objects possibly built using different programming languages. | | | Component Object Model (COM) specifies a binary standard for object interaction and supports remote object invocation. | | | Although a server usually returns an object reference representing an object instance that it is hosting, it can also return an object reference that it has obtained from another machine. |

| | Component Object Model |
| | A COM Object (also defined by a GUID, referred to in this case as a class id) is created by a call to a Win32 API (CoCreateInstance), and what is returned is a pointer to a specific interface. | | | Underpining much of Microsoft's development strategies in the last two or three years is the Component Object Model or COM. | | | One object can implement many different interfaces: each interface includes the QueryInterface method that lets you find another interface on the same object. |

| | In fact, the object model is so flexible that applications can query the COM object at run-time as to what functionality it provides. | | | His expertise spans enterprise component architectures and distributed object computing. | | | Distributed Computing purists will attest to the fact that marshalling is the process of packaging and transmitting data between different address spaces, automatically resolving pointer problems, preserving the data’s original form and integrity. |

| | Component Object Model (COM) is Microsoft's framework for developing and supporting program component objects. | | | It is aimed at providing similar capabilities to those defined in the Common Object Request Broker Architecture (CORBA), a framework for the interoperation of distributed objects in a network that is supported by other major companies in the computer industry. | | | COM includes COM+, Distributed Component Object Model (DCOM), and ActiveX interfaces and programming tools. |

| | Otaku, Cedric's weblog: Java Component Object Model |
| | Adding features to an existing plug-in didn't require understanding the existing code base: all you need to do is read some documentation about the area that your plug-in will depend on and focus on that part only. | | | In a previous entry, I discussed how using mix-ins lets you compose your code to a finer level and allows you to create smaller bundles of functionalities that you can import and use on demand. | | | It should be as simple as possible to implement and as properly defined and structured so that can be extended in future, something like that. |

| | What is Component Object Model? - A Word Definition From the Webopedia Computer Dictionary |
| | COM objects are more versatile than Win32 DLLs because they are completely language-independent, have built-in interprocess communications capability, and easily fit into an object-oriented program design. | | | A software architecture developed by Microsoft to build component-based applications. | | | COM objects are discrete components, each with a unique identity, which expose interfaces that allow applications and other components to access their features. |
