DCOM (Distributed Component Object Model) is a Microsoft technology that facilitates communication between software components on different computers across a network. It is a proprietary extension of the Component Object Model (COM), which is a binary-interface standard for software componentry introduced by Microsoft in the early 1990s.
DCOM enables developers to create distributed applications that can interact with objects or components residing on other computers, even if they are running different operating systems or programming languages. This allows for the development of complex, scalable, and interoperable distributed systems.
DCOM technology works by providing a set of protocols and services that allow objects to invoke methods and exchange data remotely on a network. It utilizes remote procedure call (RPC) mechanisms to enable the invocation of methods located on remote servers as if they were local objects. DCOM uses a client-server model, where the client sends a request to the server and waits for a response, enabling distributed communication and coordination.
By providing a transparent and seamless method for accessing and interacting with remote objects, DCOM simplifies the development of distributed applications, reducing the complexity of building distributed systems. It supports features such as object activation, object location, security, and object persistence, ensuring efficient and secure distribution of components.
DCOM is commonly used in enterprise-level applications, where distributed systems are required to communicate and coordinate with one another.
