40 new devices, nobody counted
Over one term, Fernside School adds smart lights, door sensors (small parts that detect things), room thermometers and cameras. Each one joins the school network (its joined-up computers and devices).
In a year, nobody knows how many there are, who set them up or whether they have ever been updated. Today you learn how to manage them.

Devices, gateways and the services behind them
Some smart devices join Wi-Fi directly. Others talk over a short-range link to a gateway, which joins the network for them.
Most devices also use a service run by their maker, often in the cloud. The service stores the readings and sends the app on your phone its updates. So a manager must also know where that data goes.
