sündmuspõhist

Sündmuspõhine, sometimes translated as event-driven, refers to a paradigm in computer programming and system design where the flow of the program is determined by events. These events can be user actions, sensor outputs, or messages from other programs or threads. When an event occurs, the system responds by executing a specific piece of code, often called an event handler or callback function. This contrasts with traditional procedural programming, where the program executes a series of instructions sequentially.

The sündmuspõhine model is characterized by its asynchronous nature. Instead of waiting for a task to complete before moving on, the system can continue to perform other operations while waiting for an event to occur. This allows for more responsive and efficient applications, especially in environments with many concurrent operations or user interactions. Common examples include graphical user interfaces (GUIs), where button clicks or mouse movements trigger events, and web servers, which respond to incoming requests.

Key components of a sündmuspõhine system include an event loop, which continuously monitors for events, and event handlers, which are registered to respond to specific types of events. When an event is detected, the event loop dispatches it to the appropriate handler. This architectural pattern is widely used in modern software development due to its scalability and ability to manage complex interactions efficiently. It is particularly relevant in areas such as real-time systems, embedded systems, and distributed computing.
