Asynchronous I/O is a form of input/output processing that allows a program to initiate an I/O operation and continue processing other tasks before the I/O operation completes. Unlike non‑blocking I/O, which returns control immediately but may require repeated polling, asynchronous I/O enables the system or API to notify the program when the operation finishes.
