ASYNC IO

Asynchronous I/O (Async I/O) is a way for computers to handle multiple input and output tasks efficiently. Instead of waiting for one task—like reading a file or retrieving data from a server—to finish before moving on, Async I/O allows the system to start these tasks and then continue with other work. Once a task is complete, the system is notified and can handle the result. This approach improves performance, especially in applications that rely on many external data sources or tasks, by making better use of system resources and reducing idle time.
