A network with one primary and four secondary stations uses polling?

In a network with one primary and four secondary stations using polling, the primary station controls communication by sequentially polling each secondary station to check if it has data to send. This method ensures organized access to the shared medium, preventing collisions and allowing efficient data transmission. The primary station typically allocates time slots for each secondary station, optimizing the use of the network resources. If a secondary station has no data to send, it simply informs the primary, allowing the primary to move on to the next station.
