A means of Media Access Control where a device may only transmit information when it is given permission to transmit by a controller device.

Procedure for collecting data from meter panel homes, usually by means of a telephone call from the central processing base of the data supplier, which downloads in the early hours of the morning meter data from the previous broadcast day(s) via a modem connection with the central meter data storage unit in the home. Alternative cellular radio or o [..]

A technique a CPU can use to learn if a peripheral device is ready to receive data or to send data. In this method each device is checked or polled in-turn to determine if that device needs service. T [..]

Network control in which the control station invites tributary stations to transmit in the sequence specified by the control station. 2. In point-to-point or multipoint communication, the process whereby stations are invited one at a time to transmit. 3. Sequential interrogation of devices for various purposes, such as avoiding contention, determin [..]

(1) Polling is a CAM. In a master/slave scenario, the master queries each slave device in turn as to whether it has any data to transmit. If the slave answers yes then the device is permitted to trans [..]

A feature which permits a fax machine to call another machine and request it to transmit documents. Pages must be left in the document feeder or in memory and the polling unit must have the passcode of the unit it is calling.

Allows the unit to call remote locations and retrieve any waiting faxes.

The process of a fax machine calling another fax machine to retrieve waiting fax messages.

Usually refers to some form of data network arrangement whereby a central computer asks each remote location in turn (and very quickly) whether they want to send some inf [..]

  Checking the status of an input line, sensor, or memory location to see if a particular external event has been registered. Typically used on fax machines to retrieve information from a remote source, the user, will dial from one fax machine to another, then press the polling button to get information from the remote fax machine. *** The Informat [..]

The process of repeatedly testing until a condition becomes true. Polling can be inefficient if the time between tests is short compared with the time it will take for the condition to become true. A [..]

Polling is the method by which the browser gets information from the server to send instant messages in Chat. The polling method for Chat is configured with the glide.short_poll_delay property.

The daily process whereby the meters send back collected data to be processed into viewing figures.

A process where a controller attempts to identify the source of an interrupt request by interrogating the peripherals connected to it.

poll|lang=en|nocat=1

A round-robin canvassing of inputs to a computer to determine which ones are active. In most cases, polling is synchronized in software to a clock or external trigger.
