Event Driven Programming is a paradigm that centers on responding to user interactions and system signals. It involves event handlers, loops, and queues to manage events efficiently, offering responsiveness and scalability. The approach faces challenges like complex dependencies and debugging issues but excels in GUIs, server-side tech, and real-time systems.

Event Driven Programming is a computational paradigm that orchestrates the flow of a program around the occurrence of various events
Event Handlers
Event handlers are functions or methods designated to respond to specific events, executing code when triggered
Event Loop
The event loop is a fundamental mechanism that continuously monitors for events and dispatches them to their respective handlers
Event Queue
The event queue acts as a buffer that collects events as they occur, preserving their order and facilitating controlled processing
Event Driven Programming offers numerous benefits, such as creating highly responsive systems, but also introduces challenges such as complex event dependencies

Event Driven Programming is utilized in GUI development to create interfaces that respond immediately to user actions
Event Driven Programming is used in server-side technologies to handle multiple client requests concurrently, optimizing throughput and reducing response times
Real-time systems rely on the prompt processing of events to maintain up-to-date states and ensure timely reactions to time-sensitive data
Event Driven Programming and Object Oriented Programming are distinct yet complementary paradigms that can be integrated to harness the benefits of both
By selectively applying the strengths of each paradigm, developers can create sophisticated applications that effectively meet a wide range of functional requirements
Combining Event Driven and Object Oriented Programming requires a thoughtful approach that aligns with the specific needs of the application
