hardware.
 Using event driven programming, programs can be easily to create
since the it easily to understand and to learn.

Example of event driven programming.

Below shows how a (very simple) scheduler might work. It consists of a
main loop that runs continuously until some terminating condition occurs.
When an event occurs, the scheduler must determine the event type, and
select an appropriate event-handler (or deal with the event, if no suitable
event-handler exists).
