sündmuspõhisest

Sündmuspõhine is an Estonian term that translates to "event-driven" in English. It describes a programming paradigm or a system architecture where the flow of control is determined by the occurrence of events. An event can be anything from a user clicking a button to a sensor detecting a change or a message arriving from another system.

In an event-driven system, components or modules do not actively poll for changes or instructions. Instead, they register themselves as listeners for specific types of events. When an event occurs, the system generates a notification, and all registered listeners that are interested in that particular event are alerted. These listeners then execute predefined actions or routines in response to the event. This contrasts with traditional procedural programming, where a program follows a predetermined sequence of instructions.

Event-driven architectures are common in user interfaces, where user actions trigger responses. They are also prevalent in real-time systems, robotics, and distributed systems where asynchronous communication and responsiveness are crucial. The benefits of this approach include improved responsiveness, modularity, and scalability, as components can be added or removed without significantly impacting the rest of the system. The core idea is that the system reacts to stimuli rather than dictating a fixed execution path.
