Polling is a technique in which one device continually monitors multiple other devices or makes requests from those devices, usually one after the other. Polling may also be done randomly or according to a predefined schedule. Polling is used by management applications to check the state of devices. It may read status information, then add that information to a log file or database for future reference. Many multiport network devices use polling techniques to check the status of ports or to service nodes attached to those ports. Each port may be serviced one after the other in a fair way, or some ports may be given priority service. Queue managers use polling techniques to service queues. See "Queuing."
