Morphology

poller = poll (semi-transparent) = poll + er

Formed by the productive agentive suffix '-er' from the verb 'poll', but the computing sense 'to check status' is specialized and may be less familiar to average learners.

Etymology

The word poller comes from the old word poll, which meant 'head' and then 'to count heads' or votes. In computing a poller is a program or device that 'asks' a server again and again to check its status, so the old idea of counting helps explain why a poller keeps checking for updates.
