An operating system in which the interrupt system is the mechanism for reporting all changes in the states of hardware and software resources, and such changes are the events that induce new assignments of these resorces to meet work-load demands.

Why Visual Basic is event-driven programming?

In an event-driven application the code doesn’t follow a pre determined path rather it execute different code sections in response to events. They either act on an object or are triggered by an object to control the flow of execution when it is running. That is why VB called Event-Driven programming language.

How does an event-driven application differ from a traditional request driven application?

The request-driven approach, for example, gives greater control of action via its command-driven and structured approach, whilst the event-driven model gives greater flexibility, supporting real-time, business-driven events.

Which operating system uses the command driven interface?

The MS-DOS operating system and the command shell in the Windows operating system are examples of command-line interfaces.
