Hence its faster compared to other databases, Rather than that its support more than 20 programming language support for integration.

Its process of data and return the computed values. Replication is the act of sync data between multiple servers, which makes MongoDB as high availability. Using Gridfs is the specification used for storing and retrieving the audio or video file from MongoDB. It huge interconnected network between the objects to detect the different scenarios. Ans: More applications are there in IOT technology few are i. Ans: As name suggest internet network plays an important in IOT implementation to connect the millions of the objects to each other.

Ans: Yes, Because of as per telecommunication era is becoming extra broadband, giant and efficient internet broadly available, The hardware cost become less expensive. Ans:Hardware: This will makes the normal devices as intelligent and smart devices, read the data in time Software: Process the collected and store data from the device and it manipulate as the requirement Infrastructure: Here it more essential communication infrastructure which are Technology and protocols to exchange the data.

Ans: More hardware prototype devices are in implementation of IOT i.

IoT Interview Questions and Answers

Answer: 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 one? 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. Another very relevant example is provided by W. 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 communication in the internet of things realm can be made truly secure.

You can easily and cheaply buy sensors that can measure a variety of variables that would be interesting in industrial applications, for example and this is for sure not a complete list : light or sound intensity; voltage; current; pressure; temperature; rotational position; XYZ orientation; compass direction; acceleration; location; fluid flow rate and so on. These sensors can be interrogated by microcontroller, and data stored to memory card, or communicated in realtime to other systems via Bluetooth, Zigbee, WiFi , Ethernet, serial, USB, infared and so on. 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. The world is building more and more intelligent machines that interact with other machines, with their environments, with data centers and with humans. Counted as the most mature wireless radio technology, Wi-Fi is predominant communication technology chosen for IoT applications. Already existing protocols like WPS make the integration of internet of things devices easier with the existing network.
