Message Passing
Message passing is a communication paradigm in computer science where processes or objects exchange messages to coordinate actions and share data, often used in concurrent, distributed, and parallel systems. It enables decoupled components to interact without shared memory, promoting modularity and scalability. Common implementations include inter-process communication (IPC), actor models, and message queues in distributed architectures.
Developers should learn message passing when building systems that require high concurrency, fault tolerance, or distributed coordination, such as microservices, real-time applications, or cloud-based platforms. It is essential for avoiding shared-state issues in multi-threaded environments and for enabling communication across network boundaries in scalable applications.
