Exploring the World of IoT

What is the primary vision of IoT?

• To create isolated systems that do not share data.

• To reduce the number of devices connected to the internet.

• To create a connected ecosystem of devices that communicate and share data.

• To limit device communication to a single network.

How does IoT differ from M2M communication?

• IoT and M2M are the same and interchangeable terms.

• M2M focuses on cloud computing and big data analytics.

• IoT is only about connecting household appliances without any data exchange.

• IoT is broader and includes M2M as a subset, focusing on internet connectivity and data exchange, while M2M is limited to direct device communication.

What are the key components of IoT architecture?

• Sensors and Actuators

• User Interfaces

• Devices, Connectivity, Edge Computing, Cloud Computing, Applications

• Data Encryption

Can you name the different layers in an IoT system?

• User interface layer

• Security layer

• Transport layer

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

What role does standardization play in IoT design?

• Standardization limits the number of devices that can connect.

• Standardization enables interoperability and compatibility among IoT devices.

• Standardization has no impact on device performance.

• Standardization increases the cost of IoT devices.

Which communication technologies are commonly used in IoT?

• Ethernet

• NFC

• Wi-Fi, Bluetooth, Zigbee, Z-Wave, Cellular, LoRaWAN

• Infrared

Aarush is developing an IoT application for smart home automation. What are some common sources of data he might use in his application?

• User interfaces and dashboards

• Sensors, devices, and gateways.

• Cloud storage and databases

• Network protocols and standards

How is real-time data handled in IoT systems?

• Real-time data is collected by sensors, processed locally or in the cloud, and transmitted using communication protocols for immediate analysis.

• Real-time data is stored in a database for later retrieval.

• Real-time data is ignored to save processing power.

• Real-time data is only analyzed once a day.

What are the main applications of IoT in everyday life?

• Online shopping websites

• Social media platforms

• Smart home devices, wearable health monitors, smart appliances, connected vehicles, environmental monitoring.

• Video streaming services

Why is interoperability important in IoT?

• Interoperability is important in IoT because it enables seamless communication and collaboration between diverse devices and systems.

• Interoperability is only necessary for large-scale IoT systems.

• Interoperability complicates device communication and slows down processes.

• Interoperability is irrelevant as each device operates independently.
