Description: Communication between modules in a microkernel architecture refers to the interaction and exchange of information between different components or modules that operate independently within the system. In this approach, the microkernel acts as a minimalist core that provides only essential functions, such as process management and inter-module communication, while additional functionalities, such as device drivers and file systems, are implemented as separate modules. This separation allows modules to communicate with each other through well-defined interfaces, facilitating interoperability and scalability of the system. Communication can occur via messages, where one module sends data to another, or through remote procedure calls (RPC), which allow one module to invoke functions in another module as if they were in the same memory space. This modular architecture enhances the security and stability of the system by isolating failures in individual modules and allows for easier updates and maintenance, as modules can be modified or replaced without affecting the core of the system. In summary, communication between modules is a fundamental aspect of microkernels, promoting a flexible and robust design in modern computing systems.
