[Get] 2018 Top IoT Interview Question and Answers PDF 1. What Is IoT? Ans. IoT stands for Internet of Things. It is basically a network using which things can communicate with each other using internet as means of communication between them. All the things should be IP protocol enabled in order to have this concept possible. Not one but multiple technologies are involved to make IoT a great success. 2. What Role Does The Network Play In The Internet Of Everything? Ans. The network plays a critical role in the Internet of Everything? It must provide an intelligent, manageable, secure infrastructure that can scale to support billions of context-aware devices. 3. How Does The Internet Of Everything Relate To The Internet Of Things? Ans. The “Internet of Everything” builds on the foundation of the “Internet of Things” by adding network intelligence that allows convergence, orchestration and visibility across previously disparate systems. 4. What Is The Difference Between The Internet Of Things (IoT ) And The Sensor Business? Ans. Sensors can be used in lots of different ways, many of which don’t need to be internet connected. IoT also includes the control side, not just the sensing side.
5. What Are the Main Challenges of Internet of Things (iot)? Ans. Like any other technology there are challenges which make the viability of IoT doubtful. Security is one of the major concerns of experts who believe virtually endless connected devices and information sharing can severely compromise ones security and wellbeing. Unlike other hacking episodes which compromise online data and privacy with IoT devices can open gateway for an entire network to be hacked.

One such flaw is well presented by Andy Greenberg on wired.com where he works with hackers to remotely kill his Jeep on the highway. Another very relevant example is provided by W. David Stephenson in his post Amazon Echo: is it the smart home Trojan horse? You can estimate the amount of personal and private data the connected devices will be producing once they are on a network. The major challenge for IoT tech companies is to figure out how the communication in the internet of things realm can be made truly secure. 6. What Is The Internet Of Everything? Ans. The Internet of Everything is the intelligent connection of people, process, data and things. 7. How the Internet of Things (IoT) Make a Difference to the Businesses? Ans. Businesses focus on getting products to the marketplace faster, adapting to regulatory requirements, increasing efficiency, and most importantly, persisting to innovate. With a highly mobile workforce, evolving customer, and changing supply chain demand, the IoT can move your enterprise forward, starting today. 8. Why Is The Internet Of Everything Happening Now? Ans. The explosion of new connections joining the Internet of Everything is driven by the development of IP-enabled devices, the increase in global broadband availability and the advent of IPv6. 9. What Companies Are Working On Internet of Things (IoT)? Ans. At this point, the easier question might be who isn’t working on an IoT product. Big names like Samsung, LG, Apple, Google, Lowers and Philips are all working on connected devices, as are many smaller companies and startups. Research group Gartner predicts that 4.9 billion connected devices will be in use this year, and the number will reach 25 billion by 2020. 10. Why Is The Internet Of Everything Important? Ans. The Internet of Everything brings together people, process, data and things to make networked connections more relevant and valuable than ever before – turning information into actions that create new capabilities, richer experiences and unprecedented economic opportunity for businesses, individuals and countries.

Some important considerations in the Internet of Everything include privacy, security, energy consumption and network congestion. 12. What Is Bluegiga Apx4 Protocol for Internet of Things (iot)? Ans. BLE and Wi-Fi together can be used without interference as they are compliable to coexistence protocols. The Bluegiga APx4 is one such solution which supports both BLE and Wi-Fi and is based on 450MHz ARM9 processor. 13. What Is Zigbee Protocol for Internet of Things (iot)?

Ans. ZigBee is a low power consuming IEEE 802.15.4(2003) standard based specification, ZigBee is a brain child of 16 automation companies. What makes it novel is the use of mesh networking which makes utilization of communication resources much more efficient. ZigBee based IoT nodes can connect to central controller making use of in-between nodes for propagating the data. It makes transmission and handling of data robust. 14. Is The Internet Of Everythi ng A Cisco Or Ibm Architecture Or Trademark? Ans. No. The Internet of Everything does not describe a specific architecture and is not solely owned by Cisco or IBM or any other company. 15. What Is Industrial Internet of Things (iot)? Ans. The Industrial Internet of Things (IIoT) is the use of Internet of Things (IoT) technologies in manufacturing. Also known as the Industrial Internet, IIoT incorporates machine learning and big data technology, harnessing the sensor data, machine-to-machine (M2M) communication and automation technologies that have existed in industrial settings for years. The driving philosophy behind the IIoT is that smart machines are better than humans at accurately, consistently capturing and communicating data. This data can enable companies to pick up on inefficiencies and problems sooner, saving time and money and supporting business intelligence efforts. In manufacturing specifically, IIoT holds great potential for quality control, sustainable and green practices, supply chain traceability and overall supply chain efficiency. 16. How High-speed Internet Might Affect the Development and Implementation of the Internet of Things (iot)? Ans. Use and growth of the IoT can also be limited by the availability of access to high-speed Internet and advanced telecommunications services, commonly known as broadband, on which it depends. While many urban and suburban areas have access, that is not the case for many rural areas, for which private-sector providers may not find establishment of the required infrastructure profitable, and government programs may be limited. 17. What Risks And Challenges Should Be Considered In The Internet Of Everything? Ans. Some important considerations in the Internet of Everything include privacy, security, energy consumption and network congestion. 18. What Is Gainspan Gs2000 Protocol for Internet of Things (iot)? Ans. GainSpan GS2000 is one such tech which used both ZigBee and Wi-Fi. It makes optimum use of power by putting the device into energy-saving standby mode when no data transmission is taking place. Only when device is awaked or checked for connection failure the high power consumption connection of Wi-Fi is used. 19. How will IoT benefit the end-users? Ans. IoT is continuously changing the way we live, work and entertain. Because of IoT, immense opportunities and possibilities are being created for businesses to innovate in services and products. It

has the potential of impacting all the aspects of an end-user’s life. Devices are being made context-aware by embedding intelligence into them. And not just devices, we are also embedding intelligence into the environment, and through this embedded intelligence we are enabling it to capture real-time data. This harnessing of intelligence will definitely enhance and augment human capabilities to understand and improve the quality of their lives. 20. What is the top M2M application that is available in the world? Ans. The acronym M2M application stands for Machine to Machine applications.
