IoT Introduction :- The Internet of Things (IoT) describes the network of physical objects(things)that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now connected to the internet, all collecting and sharing data. It's possible to turn anything, from something as small as a pill to something as big as an aeroplane, into a part of the IoT. The Internet of Things is making the fabric of the world around us more smarter and more responsive, merging the digital and physical universes.
