What are the components of the IoT?

IoT architecture is made up of the hardware, networks, and cloud technologies that enable interoperability between IoT devices. A fundamental IoT architecture has three layers: Perception (the sensors, gadgets, and other technologies) (the sensors, gadgets, and other devices) Network (the link between devices) (the connectivity between devices)

What is the state of IoT right now?

The chip shortage continues to hinder the Internet of Things (IoT) market recovery, according to our current State of IoT-Spring 2022 research, released in May 2022. To reach 12.2 billion active endpoints, the total number of IoT connections increased by 8% in 2021, a much slower rate of growth than in prior years.
