Define IoT. Explain the vision of Internet of Things (IoT).

IoT, or Internet of Things, is a system of interrelated physical devices, vehicles, buildings, and other objects embedded with sensors, software, network connectivity, and necessary electronics that enables these objects to collect and exchange data.

The vision of the Internet of Things (IoT) is to create a world where every object, from jumbo jets to sewing needles, is connected to the internet. This vision includes not only physical objects, but also virtual ones like social media accounts or digital platforms.

The idea is that not only can objects communicate with people, but they can also communicate with each other. For example, your car could communicate with other cars on the road to optimize traffic flow, or your fridge could communicate with your online grocery store to order more milk when it's running low.

This vision is based on the belief that if all objects and people in daily life were connected to the internet, it would be possible to provide seamless communication and coordination between people, processes, and technology. This could lead to improved efficiency, accuracy, and economic benefit.

In summary, the vision of IoT is to create a world where every object, physical or virtual, is interconnected, creating a seamless network of communication and coordination.
