What is the essence of the Internet of Things (IoT)?

The essence of the Internet of Things (IoT) lies in data interaction through connected devices. IoT fundamentally refers to the network of physical objects—devices, vehicles, appliances—that are embedded with sensors, software, and other technologies, and are capable of connecting to the internet to collect and exchange data. This capability allows for seamless communication between devices, enabling them to share information and automate processes based on the data they receive and analyse.

This interaction is what distinguishes IoT from other networking or connectivity concepts, as it emphasizes the significance of data generation, transmission, and utilization to foster smart environments. It allows for real-time data analysis and decision-making, leading to improved efficiency and smarter applications in various fields such as smart homes, healthcare, and industrial automation. Hence, the focus on data interaction is central to understanding the core principle of IoT.
