Explain the difference between IoT communication models.

• The main IoT communication models are Device-to-Device (D2D), Device-to-Cloud (D2C), and Device-to-Gateway (D2G).

• Device-to-Application (D2A)

• Device-to-User (D2U)

• Device-to-Server (D2S)

What role do APIs play in IoT communication?

• APIs are used to power IoT devices directly without servers.

• APIs only serve as a user interface for IoT applications.

• APIs enable communication and data exchange between IoT devices and servers.

• APIs are primarily for data storage in IoT systems.

• HTTP, FTP

• Zigbee, Bluetooth

• MQTT, CoAP

• TCP, UDP

What is an embedded system in the context of IoT?

• A cloud-based system that stores large amounts of data.

• A type of software that runs on smartphones.

• A general-purpose computer used for various applications.

• An embedded system in IoT is a dedicated computing system that collects, processes, and communicates data.

Identify the different levels of IoT architecture.

• Device layer, Network layer, Edge computing layer, Cloud layer, Application layer

• Transport layer

• Data processing layer

• User interface layer

What is the purpose of IoT templates?

• To enhance the security of IoT devices.

• To limit the functionality of IoT systems.

• To simplify the development and deployment of IoT applications.

• To increase the cost of IoT applications.
