IOT Interview Questions and Answers Set-9

81. What is a “Thing” in the context of the Internet of Things (IoT)?

The “thing” commonly stated via the idea of the internet of things is any object that could contain an embedded, connected computing device. The “thing” within the IoT might be a delivery field with an rfid tag or a client’s watch with a wifi chip that sends fitness information or brief messages to a server someplace at the net.

82. What are the main parts of IoT systems?     

IoT system consists of three main parts:

  • Sensors
  • Network connectivity
  • Data storage applications.

83. What are security concerns related to IoT?

This is the common IoT Interview Questions asked in an interview. Data security and privacy are major concerns related to IoT. These devices are vulnerable to hacking and cloud endpoints could be used by hackers to attack servers. Software developers and device designers have to ensure adequate security and privacy measures.

84. How the Internet of Things (IoT) makes a difference to the businesses?

Agencies focus on getting products to the marketplace quicker, adapting to regulatory requirements, growing performance, and most importantly, persisting to innovate. With an incredibly cellular group of workers, evolving client, and changing supply chain demand, the IoT can circulate your corporation forward, starting today.

85. What are the risks and challenges that we should be aware of when it comes to the Internet of Everything?

The risks factors that are associated with IOT that we should be aware of are:

  • Privacy
  • Network congestion
  • Security
  • Electricity consumption at the peaks

86. What are the major Privacy and Security Issues in case of Internet Of Things (IoT)?

Cyber attacks may also compromise privacy, resulting in access to and exfiltration of identifying or other sensitive information about an individual. For example, an intrusion into a wearable device might permit exfiltration of information about the location, activities, or even the health of the wearer.

87. Explain the IoT protocol stack?   

IoT has 4 protocol layers:

  • Sensing and information: Includes various smart sensor devices based on GPS, RFID, Wi-Fi etc.
  • Network connectivity: Layer is based on a wired and wireless network such as WLAN, WMAN, Ethernet, optical fiber and more.
  • Information processing layer
  • Application layer

88. What is Bluetooth Low Energy (BLE) Protocol for an Internet of Things (IoT)?

Nokia originally introduced this protocol as wibree in 2006. Additionally known as Bluetooth smart this protocol presents the same range coverage with a good deal of decreased strength intake because of the unique Bluetooth. It has comparable bandwidth with narrow spacing as utilized by Zigbee. Low electricity latency and decrease complexity makeable greater appropriate to include into low-cost microcontrollers.

89. Why is Zigbee protocol so important for the Internet of Things implementation?

Zigbee protocol is well known for its minimum power consumption; it maintains IEEE 802.15.4(2003) standards while utilization.

90. What impacts will the Internet of Things (IoT) have?

Many observers predict that the boom of the IoT will bring fantastic blessings via greater integration, efficiency, and productiveness across many sectors of U.S. and global economies.

Among those typically cited are agriculture, energy, healthcare, manufacturing, and transportation. Tremendous impacts may also be felt greater broadly on monetary growth, infrastructure and cities, and man or woman clients. However, each coverage and technical demanding situations, consisting of protection and privateness troubles, would possibly inhibit the growth and effect of IoT improvements.
