Exploring the Internet of Things

What are the main IoT communication models?

• Device-to-User (D2U)

• Device-to-Device (D2D), Device-to-Cloud (D2C), Device-to-Gateway (D2G)

• Device-to-Application (D2A)

• Device-to-Server (D2S)

Define the term 'IoT Protocols' and give examples.

• Examples of IoT Protocols include MQTT, CoAP, and HTTP.

• FTP, SNMP, and SMTP

• TCP, UDP, and IP

• Bluetooth, Zigbee, and Wi-Fi

What role do sensors play in IoT systems?

• Sensors provide power to IoT devices without data collection.

• Sensors only monitor device performance in IoT systems.

• Sensors collect and convert environmental data into digital signals for IoT systems.

• Sensors are used solely for data storage in IoT systems.

Explain the function of actuators in IoT applications.

• Actuators convert electrical signals into physical actions in IoT applications.

• Actuators primarily process data in IoT systems.

• Actuators are used to transmit signals between devices.

• Actuators store energy for IoT devices.

What is a Wireless Sensor Network (WSN)?

• A Wireless Sensor Network (WSN) is a type of wired communication system.

• A Wireless Sensor Network (WSN) is a network of spatially distributed sensors that collect and transmit data wirelessly.

• A Wireless Sensor Network (WSN) consists of only one sensor that collects data.

• A Wireless Sensor Network (WSN) is a network of computers that process data locally.

How does cloud computing enhance IoT capabilities?

• Cloud computing limits data storage for IoT applications.

• Cloud computing reduces the need for IoT devices.
