IDL (Interface Definition Language)

Interface Definition Language (IDL) is a formal way to specify how different software components communicate with each other, especially across different systems or programming languages. It defines the methods, data types, and message formats that allow independent programs to exchange information seamlessly. Think of IDL as a common contract or blueprint that ensures both sender and receiver understand each other correctly, even if they are built with different technologies. This standardization simplifies complex distributed systems, enabling interoperability and reliable data exchange.
