The Internet of Things (IoT) is a virtual network where every objects, whether a person or an animal, everything is assigned and recognized by a unique address (Technically known as IP address) and has an amazing ability to transfer and receive data over a network without any sort of communication between human-to-computer or human-to-human. It allows objects to be sensed and controlled across the sphere, crafting great opportunities to connect with the physical world into computer-based systems, and resulting in enhanced adeptness, accuracy and economic benefit.
It is evolved from the power of the Internet, micro-electromechanical signals, and wireless technologies. In the IoT, things can be heart monitoring implants, electric clams in coastal waters, DNA analysis devices for food/pathogen monitoring, or an automobile with in-built sensors that alerts the driver in case of anything wrong suspect. In another word, it can be anything (natural or man-made objects) that can be assigned a unique IP address.
