eseményalapon

Eseményalapon is a Hungarian term that translates to "event-based" in English. It is often used in contexts related to computer science, programming, and system design to describe a paradigm where actions or processes are triggered by the occurrence of specific events. This approach contrasts with traditional procedural or polling-based methods where a program might continuously check for conditions or execute a fixed sequence of instructions.

In an event-based system, components or modules register their interest in certain events. When an event occurs, such as a user clicking a button, a network packet arriving, or a timer expiring, the system notifies all registered listeners. These listeners then execute their corresponding event handlers, which are specific pieces of code designed to respond to that particular event. This asynchronous and reactive nature allows for more efficient resource utilization, as the system only performs work when something actually happens.

Common applications of the event-based model include graphical user interfaces (GUIs), where user interactions generate events; network programming, where incoming data triggers processing; and real-time systems, where external stimuli require immediate responses. The event-based approach promotes modularity and decoupling, as different parts of a system can operate independently, reacting only to the events they are concerned with. This can lead to more flexible and scalable software architectures.
