1. IoT (Internet of Things)

2. Definition
The internet of things (IoT) is the internetworking of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data

3. IoT functions

4. Things in IoT
"Things," in the IoT sense, can refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters, automobiles with built-in sensors, DNA analysis devices for environmental/food/pathogen monitoring or field operation devices that assist firefighters in search and rescue operations.[

5. Applications

6. A case on Gas and Gas Station
Kwik Chek’s new technologies connect its customers’ mobile phones to gas pumps, store point of sale
(POS) terminals, loyalty programs and more, while integrating existing store infrastructure and software that tracks inventory and fuel.
The resulting connected system is transforming operations for the Texas-based chain, vastly improving reliability and efficiency of its processes and staff. It’s also enabling unprecedented insight into customer habits and desires, resulting in improved sales and inventory for Kwik Chek, and happier and more loyal customers across its 39 store locations in Texas and Oklahoma.

7. Future Applications
According to Gartner, Inc. (a technology research and advisory corporation), there will be nearly 20.8 billion devices on the internet of things by 2020.[44] ABI Research estimates that more than 30 billion devices will be wirelessly connected to the internet of things by 2020.
As per a recent survey and study done by Pew Research Internet Project, a large majority of the technology experts and engaged Internet users who responded—83 percent—agreed with the notion that the Internet/Cloud of Things, embedded and wearable computing (and the corresponding dynamic systems) will have widespread and beneficial effects by 2025.
As such, it is clear that the IoT will consist of a very large number of devices being connected to the Internet. In an active move to accommodate new and emerging technological innovation, the UK Government, in their 2015 budget, allocated £40,000,000 towards research into the internet of things.
The former British Chancellor of the Exchequer George Osborne, posited that the internet of things is the next stage of the information revolution and referenced the inter-connectivity of everything from urban transport to medical devices to household appliances.
