Eventbasiertem

Eventbasiertem, often translated as event-driven, refers to a programming paradigm where the flow of control is determined by events. An event is an occurrence that the system detects and responds to. These events can originate from various sources, including user actions like mouse clicks or keystrokes, system processes such as sensor readings or network messages, or even internal program states.

In an event-based system, components or modules typically register their interest in specific types of events. When an event occurs, a central mechanism, often called an event dispatcher or event loop, identifies which components are listening for that event and delivers it to them. The registered components then execute their predefined logic in response to the received event. This contrasts with traditional imperative programming, where the program's execution follows a predetermined sequence of instructions.

This paradigm is widely used in graphical user interfaces (GUIs) to handle user interactions. For example, clicking a button triggers a click event, which is then processed by the button's associated event handler. Event-driven architecture is also prevalent in real-time systems, distributed systems, and asynchronous programming, enabling systems to react dynamically to changing conditions and external stimuli without constant polling. The decoupled nature of event-based systems can lead to more modular, flexible, and responsive applications.
