In an IoT network, what is the role of a hub or router?

In an IoT setup, the hub or router’s main job is to move information from devices to the network and back. It connects sensors and actuators to the local network and serves as the bridge to the internet or to a central server, using addressing and routing to forward data to the right destination and then deliver responses to the correct device. It isn’t responsible for storing data locally or generating new sensor readings, and it doesn’t analyze data itself—that work happens in gateways, edge processors, or cloud services after the data is routed. Some hubs can do protocol translation or basic security tasks, but the core idea is that they forward data between devices and the network.
