Question

Quizplus · Accepted Answer

Polling is a technique used in computer networking where a central device (usually a hub, switch or router) sends out a request or "poll" to individual devices (nodes or clients) on the network, asking if they need to transmit any data. Only one device may transmit at a time, and all others must wait until their turn. Therefore, polling does not permit all clients to transmit or receive at any time.
