Asynchronous I/O

Asynchronous I/O is a method where a computer program can start a task, like reading a file or waiting for data, and then move on to other tasks without waiting for that initial task to finish. When the data is ready, the program is notified and can process it. This approach improves efficiency by allowing multiple operations to happen simultaneously, reducing idle time and making better use of resources. Essentially, it enables programs to handle multiple tasks smoothly without getting stuck waiting for slow operations to complete.
