The way in which an IoT device is associated with data is Cloud.

Explanation:

When you use an IoT device, such as a smart speaker or a thermostat, you are not just interacting with the physical gadget. You are also sending and receiving data to and from a remote server, usually hosted by the device maker or a third-party service. This is what we call the Cloud, and it is where most of the processing and storage of your IoT data happens.

The Cloud enables your IoT device to access online resources, such as music streaming, weather updates, or voice recognition, and to sync with other devices on the same network.

The Cloud also allows you to control your IoT device remotely from your smartphone or computer, as long as they are connected to the internet.
