The Internet of Things (IoT) is a computing concept that describes the idea of everyday physical objects being connected to the internet and being able to identify themselves to other devices. The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems. "Things", in the IoT sense, can refer to a wide variety of devices on or in humans, animals, products and other objects, allowing them to become "smart". IoT can help organizations with tracking behavior, enhanced situational awareness (ESA), sensor-driven decision analytics, process optimization and more. Today's practical applications of IoT can be found in smart home, wearables, connected cars, smart cities, smart farming, smart retail and more.
