esemenényalapú

Eseményalapú is a Hungarian term that translates to "event-driven" in English. It describes a programming paradigm and a system architecture where the flow of control is determined by a sequence of events. In this model, components of a system react to stimuli, or events, that occur over time. These events can originate from various sources, such as user interactions, sensor readings, or messages from other systems.

In an event-driven system, there are typically producers of events and consumers that subscribe to or are interested in specific types of events. When an event occurs, it is broadcast, and any consumer that has registered for that event will be notified and will execute its corresponding logic. This contrasts with traditional procedural programming, where a program follows a predetermined sequence of instructions.

The event-driven approach is widely used in modern software development for building responsive and scalable applications. Examples include graphical user interfaces (GUIs), where user actions like mouse clicks or key presses are events that trigger specific functions. It is also prevalent in real-time systems, asynchronous communication patterns, and microservices architectures, where loose coupling and the ability to react to external changes are crucial. The core idea is that the system waits for events to happen rather than actively polling for changes.
