I would like to know what the key features of event driven programming are.?

';In computer programming, event-driven programming or event-based programming is a programming paradigm in which the flow of the program is determined by sensor outputs or user actions (mouse clicks, key presses) or messages from other programs or threads.





Event-driven programming can also be defined as an application architecture technique in which the application has a main loop which is clearly divided down to two sections: the first is event selection (or event detection), and the second is event handling. In embedded systems the same may be achieved using interrupts instead of a constantly running main loop; in that case the former portion of the architecture resides completely in hardware.';
