What is Asynchronous?

Asynchronous operations allow a program to initiate a task and then continue processing other tasks without waiting for the initial task to complete. This is often used to improve responsiveness and efficiency, especially in scenarios involving I/O operations (like reading from a disk or network), where waiting can be time-consuming. Common examples include asynchronous JavaScript requests (AJAX), non-blocking I/O in operating systems, and message queues for inter-process communication.
