What does the Internet of Things (IoT) encompass?

The Internet of Things (IoT) encompasses web-enabled devices that are capable of collecting and transmitting data. This definition highlights the core function of IoT devices, which is their ability to connect to the internet and communicate with other devices or systems. They utilize sensors, software, and other technologies to gather data about their environment or operational status, and this data can be shared over the network for analysis, remote monitoring, or automation purposes.

By focusing on data collection and transmission, this definition captures the essential characteristics of IoT devices, which range from simple sensors to complex systems integrated into homes, cities, and industries. Many IoT devices can operate on limited power and may not require an always-on internet connection, but when they do connect, their primary role involves sharing data to improve efficiency or inform decision-making.

Other choices do not encompass the full scope of IoT. Personal computing devices are a subset of technology and do not cover the vast range of IoT applications. While some IoT devices may require a constant internet connection, many can function with intermittent connectivity. Legacy systems, although they may be connected to the internet, typically lack the advanced capabilities associated with IoT, such as automated data collection and communication.
