The IoT works with a certain mechanism; it is the inter-networking of different elements as a whole to exchange information. All the physical devices connected to buildings, vehicles, electronic, software, sensors, actuators and network connectivity so as to transfer data from one end to the other.
A global infrastructure where we will be able to interconnect elements based upon the existing and evolving which will help in integrating systems and communicate seamlessly is all about IoT. We can have the physical devices connected to be made accessible through the internet.
Now, we are aware of the fact how the whole IoT works and how inexplicable it is. Why do we actually need IoT? A particular article by Ashton stated how wonderfully IoT can be a great aide for us to prevent a lot of things and avoid. Let's imagine a computer which will be able to understand everything based on the information collected.
In return we will be able to track and figure out replacements, repairing and recalling if needed. This will help us to work smarter and get things working a swift manner. The computers have to be built in such a way that they can feel the surroundings and respond to it accordingly and this is how the whole of IoT works.
