Asinhrono

Asinhrono is a term used in Esperanto to denote asynchronous processes or communications. It contrasts with sinhrono, which refers to synchronous, blocking actions. In general usage, asinhrono describes scenarios where an operation starts and the program continues, with the result delivered later rather than immediately blocking the flow.

Etymology and meaning: The word is formed by the negating prefix a- attached to sinhrono (synchronous), yielding asinhrono (not synchronous). In practice, asinhrono indicates non-blocking behavior, where progress can occur independently of the initiating action.

In computing, asinhrono programming enables non-blocking I/O and event-driven design. Common mechanisms include callbacks, promises or futures, and async/await constructs. This approach is widely used to keep user interfaces responsive and to improve server scalability by handling many concurrent operations without dedicating a separate thread to each task. Examples include asynchronous network requests, file I/O, and timer-based events. Different ecosystems implement asinhrono patterns through their own abstractions, such as the event loop in JavaScript or the async runtimes in Python, C#, and Rust.

Advantages and challenges: Asinhrono programming can improve responsiveness and throughput, especially under high I/O load. However, it introduces complexity in reasoning about control flow, error handling, and potential race conditions, making debugging more difficult than in synchronous code.
