What is the Exclusive Pair communication model in WebSocket APIs?

Exclusive Pair is a bidirectional, fully duplex communication model that uses a persistent connection between the client and server.

What are the components of an IoT system?

An IoT system comprises of devices, resources, and controller services.

Explain the role of resources in an IoT system.

Resources are software components on the IoT device used for accessing, processing, and storing sensor information, or controlling connected actuators.

What is the function of a Controller Service in an IoT system?
