  • Use of Sensors and Actuators
  • The Internet Gateway Use of Layers & Data Acquisition
  • Edge Information Technology
  • Use of Cloud Analytics and Data Centers.

4. Could you explain a cyber-physical system in IoT?

 Cyber-Physical Systems are a new type of computer that integrates computing elements with the physical components and processes. These computers include sensors that monitor cyber and physical indicators and actuators that modify the cyber and physical environment.

5. What are the components of cyber-physical systems?

Among the elements that make up cyber-physical systems (CPS) are theoretical models and engineering concepts from different fields, including:

  • Cybernetics
  • embedded systems
  • distributed control
    sensor networks
  • control theory
  • systems engineering

6. What is the key characteristic of cyber-physical systems?

 CPSs are characterized by a cross-cutting integration of technologies, industrial domains, and the life cycle. The integration of these elements is achieved through a highly automated process that is characterized by lifelong learning over time.

7. Could you differentiate between IoT and IoM?

 Industry 4.0 is a term used to describe the fourth industrial revolution, incorporating IoT, or the Internet of Things, and the Industrial Internet of Things (IoM), or the Internet of Manufacturing. These technologies are transforming manufacturing by creating digital factories that increase automation and traceability.

8. Are there any similarities between IoT and M2M?

While the two technologies share common aspects, they are not the same. One of the key distinctions is that Machine-to-Machine (M2M) technology enables remote access to machine data while Internet of Things (IoT) technology both exchanges information among machines and enables remote access to that data.

9. Could you elaborate on the different characteristics of M2M?

 One of M2M communication’s most important characteristics is that it uses little energy, which is why systems are more efficient when exchanging data. The network operator offers service packages, often including monitoring functions, so that users can keep track of important events.

10. How would you define IoE?

An extension of the Internet of Things (IoT), the Internet of Everything (IoE) describes a more complex system that takes into account not only machine-to-machine communication (M2M) but also human interaction.

11. What are the application areas of IoT?

  • Smart Homes.
  • Smart City
  • Self-driven Cars
  • IoT Retail Shops
  • Farming
  • Wearables
  • Smart Grids
  • Industrial Internet.

12. Can you tell me the key drivers for the growth of the internet of things across industries?

  • Artificial intelligence.
  • Advanced analytics.
  • Augmented and virtual reality.
  • Next-gen cyber security.
  • Big data.
  • Cloud computing.
  • Blockchain, and a lot more.

13. What are some of the business challenges with IoT?

  • Working with Stakeholders. 
  • Managing Remote Devices
  • Interoperability of Devices
  • Data integration
  • Handling Huge Data Volumes
  • System Flexibility
  • Data Security.

14. What are the economic impacts of the increased application of IoT?

Compared to traditional methods, IoT is significantly more productive: it increases GDP by 0.2% and is still growing. The manufacturing sector enjoys the majority of these benefits, making it the sector that has the greatest opportunity for utilizing the Internet of Things.

15. How would you explain the term IoT monetization?

 A business model for monetizing data extracted from IoT products involves marketing the knowledge gained from the data to third parties. This can even go as far as offering the IoT product to as large a mass as possible.

16. What are the three building blocks for IoT architecture?

  • The Things with Networked Sensors and Actuators
  • Raw Information and Processed Data Stores
  • Analytical and Computing

17. What are the 4 layers of IoT architecture?

  • Sensing Layer
  • Network Layer
  • Data processing Layer
  • Application Layer

18. Could you tell me the types of IoT architecture?

There are ideally only three major types namely: 

  • Application-specific
  • Open platform 
  • Network as a Service (NaaS) 

19. Which are the protocols that work in the IoT network layer?

  • RPL Protocol
  • CORPL Protocol
  • CARP Protocol
  • 6LoWPAN.

20. What are the main social impacts of the Internet of Things (IoT )?

Its goal is to create a flexible, scalable framework for developing and deploying applications on top of the IoT; it complements existing IoT standards and solutions.

24. Could you explain to me what causes IoT attacks?

If IoT devices connect to one another using insecure protocols and rely on insecure software, then the entire system can be vulnerable to attacks. A spoofing attack could send false information to an IoT device, or a DoS attack could prevent a device from receiving accurate data from its network.

25. What according to you are the largest security challenges in IoT?

 The lack of encryption on regular transmissions is one of the biggest security issues with IoT devices. This gives hackers a direct line into the network, which means they can capture passwords and other sensitive data sent to and from the device.

26. What as per your knowledge is next after IoT?

Experts agree that the digital twin is the natural successor to the Internet of Things. Today, almost all physical objects are now connected digitally either directly or indirectly. The idea behind this technological innovation is to replicate the physical world in a digital form, completely.
