DCOMs, or Distributed Component Object Model, is a Microsoft technology that allows software components to communicate over a network. It enables applications to interact with one another, regardless of where they are located, by using a standard protocol. This is particularly useful for building distributed systems where different parts of an application may run on different machines. DCOM extends the capabilities of COM (Component Object Model) by adding network support. It allows developers to create applications that can share data and services seamlessly, enhancing collaboration and efficiency in software development. DCOM is commonly used in enterprise environments for building scalable and robust applications.
