1. What does the term “Internet of things” mean? What is the origin of this term? What technology was prerequisite for the IoT?

The term "Internet of things" (IoT) refers to the network of physical objects or "things" embedded with sensors, software, and other technologies that enable them to connect and exchange data with other devices and systems over the internet. These objects can range from everyday household items like refrigerators and thermostats to industrial machinery and vehicles.

The term "Internet of things" was coined by Kevin Ashton in 1999 while working at Procter & Gamble. He used it to describe the concept of connecting devices to the internet to enable them to communicate and share data without human intervention.

The technology prerequisite for the IoT is the availability of low-cost sensors and wireless connectivity. These advancements have made it possible for devices to collect and transmit data over the internet, leading to the development of smart devices and systems that can automate tasks, improve efficiency, and provide valuable insights.
