Asynchronous communication refers to a communication method where the sender and receiver are not required to interact simultaneously. Instead, messages are sent and received independently, allowing participants to operate on their own schedules. This approach enables flexibility and decoupling in systems, as each participant can process messages at their convenience without waiting for real-time interaction.

Asynchronous communication is commonly used in distributed systems, messaging architectures, and event-driven applications. It facilitates scalability, fault tolerance, and resilience, as systems can handle varying processing times and intermittent connectivity. By decoupling components and allowing them to operate asynchronously, this communication method promotes efficiency, responsiveness, and robustness in complex software systems.
