Understand the difference between COM and DCOM to maximize their use.

What is difference between COM and DCOM?

Component Object Model (COM) and Distributed Component Object Model (DCOM) are two popular technologies used in software development. Both technologies are based on the same principles but offer different capabilities. In this article, we will look at COM and DCOM and compare the differences between them.

What is COM?

Component Object Model (COM) is an object-oriented software architecture developed by Microsoft. It provides a platform-independent interface for components in a distributed environment such as a network. COM is a powerful technology that enables software components to communicate with each other and allows them to be reused and distributed across multiple platforms.

COM is used in many software applications, such as Microsoft Office, Internet Explorer, and Windows. It is used to create reusable components that are accessible from a variety of languages and environments. COM enables developers to create components that can be used in a variety of settings across multiple platforms.

COM objects are created using programming languages such as C++ and Visual Basic. The use of COM objects makes it easier for developers to create applications that can be used on multiple platforms.

What is DCOM?

Distributed Component Object Model (DCOM) is a Microsoft extension of COM. It provides a way to access applications and components that are distributed across different networks. DCOM is based on the same principles as COM but provides additional features and capabilities for distributed applications.

DCOM provides a standard way of accessing objects on remote machines. It also provides security features, such as authentication and encryption, which are important for distributed applications. DCOM provides a platform-independent interface for distributed components, and it is used in many distributed applications.

DCOM objects are created using programming languages such as C++ and Visual Basic. DCOM objects can be accessed from multiple platforms and can be used to create distributed applications that are accessible from multiple networks.

In summary, COM and DCOM are two popular technologies used in software development. COM is an object-oriented architecture used for creating reusable components that can be used across multiple platforms. DCOM is an extension of COM that provides additional features and capabilities for distributed applications. Both technologies provide a platform-independent interface for components and are used in many software applications.
