Event Queue

An event queue is a system used in computing to manage and organize actions or tasks that need to be processed. When a computer interacts with users or external devices—like clicks, keystrokes, or messages—these events are added to the event queue. The system processes these events one at a time, in the order they arrive, ensuring that each task is handled smoothly and efficiently. This approach helps computers manage multiple inputs without confusion, maintaining an orderly flow of actions that keeps programs responsive and functioning correctly.
