What is Events?

In computing, 'Events' refer to actions or occurrences that happen in a system which the system may need to react to. Events can be user interactions (like a mouse click or a key press), system signals (like a timer expiring or a file being modified), or data updates (like a new record being added to a database). Event-driven architectures and programming models are common, where applications are structured to listen for and respond to events in real-time or near real-time. They are commonly used in graphical user interfaces, operating systems, and distributed systems to enable responsiveness, concurrency, and loose coupling between components.
