KembaraXtra-Computer Terms – autopolling:
Autopolling is a process in which a computer program repeatedly checks the status of each device connected to the system in order to determine whether any events have occurred. The program periodically queries devices such as a mouse, keyboard, or serial port to see if new data is available or if an action—such as a button press—has taken place. Once an event is detected, the program can respond accordingly. This method differs from event-driven or interrupt-driven processing, in which the operating system actively notifies the program when an event occurs instead of requiring the program to continually check each device. Autopolling is sometimes simply referred to as polling.
