event-driven processing

Event-driven processing is a way computers respond to specific actions or occurrences, called events. Instead of running tasks in a fixed order, the system waits for something to happen—like a user clicking a button, a message arriving, or a sensor detecting movement—and then reacts accordingly. This approach allows the system to be more efficient and responsive, handling activities only when needed. It’s commonly used in user interfaces, real-time systems, and applications where timely responses to changing conditions are essential. Essentially, it’s a reactive way for computers to operate based on events happening around them.
