IOT Interview Questions and Answers
Question - 101 : - What Is Industrial Internet Of Things (iot)?
Answer - 101 : -
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.
Question - 102 : - Why Should We Care About The Industrial Iot?
Answer - 102 : -
he Industrial IoT focuses strongly on intelligent cyber-physical systems. These systems comprise machines connected to computers that interpret, analyze and make decisions almost instantly, based on sensor data from many widely distributed sources.
The Industrial IoT enables the smart system in your car that brakes automatically when it detects an obstacle in the road. It enables the patient monitoring system in hospitals to track everything from a patient’s heart rate to their medication intake. It enables a mining machine or space robot to safely and efficiently operate where humans can’t.
The world is building more and more intelligent machines that interact with other machines, with their environments, with data centers and with humans.
Question - 103 : - What Is Zigbee Protocol For Internet Of Things (iot)?
Answer - 103 : -
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.
Question - 104 : - What Impacts Will The Internet Of Things (iot) Have On Manufacturing Sector?
Answer - 104 : -
Integration of IoT technologies into manufacturing and supply chain logistics is predicted to have a transformative effect on the sector. The biggest impact may be realized in optimization of operations, making manufacturing processes more efficient. Efficiencies can be achieved by connecting components of factories to optimize production, but also by connecting components of inventory and shipping for supply chain optimization.
Another application is predictive maintenance, which uses sensors to monitor machinery and factory infrastructure for damage. Resulting data can enable maintenance crews to replace parts before potentially dangerous and/or costly malfunctions occur.
Question - 105 : - Is The Internet Of Everything A Cisco Or Ibm Architecture Or Trademark?
Answer - 105 : -
No. The Internet of Everything does not describe a specific architecture and is not solely owned by Cisco or IBM or any other company.
Question - 106 : - What Effect Will The Internet Of Things (iot) Have On Our Daily Lives?
Answer - 106 : -
It already is having an impact. A recent report from Gartner says there will be 4.9bn connected things in 2015, rising to 25bn by 2020. What are these things, though?
“Let us not focus on fridges,” says Will Franks, who sold Ubiquisys to Cisco for ?204m in 2013. Franks, who has just helped set up the Wireless IoT Forum, lists a number of consumer touch points. “Keeping track of possessions where insurance companies could reduce premiums,” he says. “Home control devices, maintenance checks for cars and white goods, healthcare and so on.”
He doesn?t mention robots or Facebook. Robots will be connected too in a smart home of the future, at least according to the GSMA. And Facebook? According to The Register, it?s planning to launch software development kits (SDKs) for IoT apps and devices. Heating control through systems such as Nest and Hive are just the start, it seems.
Question - 107 : - What Is Difference Between Wireless Sensor Network (wsn) And Internet Of Things (iot) Network (sensor)?
Answer - 107 : -
About WSN:
Wireless sensor network is the foundation of IoT applications.
WSN is the network of motes, formed to observe, to study or to monitor physical parameters of desired application.
For example – Motes deployed in Agriculture land, monitor Temp-Humidity or even soil moisture, who gathers data and with perfect data analysis produce results about crop yields – quality or quantity.
About IoT:
IoT is the network of physical objects controlled and monitored over internet.
Now just as WSN, in IoT application you will encounter the monitoring of physical parameters. But desired outcomes are little different.
IoT is more about M2M, it is more about bringing smartness into daily objects.
For example – Device hooked to your Thermostat monitors surrounding temperature and adjust it to most preferred setting for
