It sounds like an incredibly complex, but putting it in simple words, the Internet of Things (IoT) is nothing but a network that connects physical objects, such as vehicles, machine tools, street lights, wearables, wind turbines, people, and other devices, via connectivity solutions in order to enable communication, exchange data, and derive actions. With the underlying goal of having access things will be in use worldwide by the end to relevant information in real time (or at of 2017, up 31 percent from 2016, and least near real time), IoT sensors trans- that the number will reach 20.4 billion by form analog inputs into digital signals and 2020.1 Dell’s CEO estimates that as many thus create a digital reflection of what as 70 billion connected devices will exist is happening in the physical world.
