What does the Internet of Things (IoT) refer to?

The Internet of Things (IoT) specifically refers to a network of physical objects that are embedded with electronics, software, sensors, and connectivity features that allow them to connect and exchange data with other devices and systems over the internet. This integration enables these objects to collect and transmit data, thus allowing for greater automation, real-time monitoring, and improved interaction between physical and digital worlds.

In this context, IoT devices can include anything from smart home appliances, like thermostats and refrigerators, to industrial machines, health monitoring equipment, and vehicles. The core concept is that these devices can communicate and work together to enhance efficiency, improve decision-making, and enable smarter environments.

Options that describe social media applications, unrelated devices, or data storage platforms do not capture the essence of IoT, which is focused specifically on the capability of connected physical objects to interact and share information.
