Which of the following best describes the Internet of Things (IoT)?

The Internet of Things (IoT) is best described as a network of interconnected devices exchanging data. This reflects the fundamental nature of IoT, which involves various devices—ranging from everyday appliances to complex industrial tools—being linked together through the internet. These devices can communicate and share data with one another, often without human intervention, enabling enhanced automation, remote monitoring, and intelligent decision-making based on the data exchanged.

The essence of IoT lies in its ability to connect devices and sensors, allowing them to gather data and interoperate to improve performance, efficiency, and user experience. As such, options describing it as a collection of software applications, an isolated computing environment, or a system for managing traditional IT operations do not accurately capture the essence of what makes IoT distinct. Rather, IoT encompasses far more than just software or isolated systems—its core is the connectivity and collaboration between devices across diverse applications and environments.
