The concept by which Internet or network connectivity, computing capabilities, and collection and exchange of data extend to everyday objects that are not computers. In the Internet of things (IoT), devices work with minimal human intervention to transform the way we work, live, and play. For example, modern thermostats, lights, refrigerators, and other appliances can all connect to IoT devices for automation. The model of combining computers, sensors, and networks for a specific purpose has existed for decades, but the advancement in technology has made the IoT more widespread (see illustration). The primary enabling technologies of the IoT are RFID (radio-frequency identification), low-energy Bluetooth/wireless/radio, NFC (near-field communication), Internet Protocol (IP)–based networking, and cloud computing. Everyday objects combined with Internet connectivity and data analytic capabilities can create a more efficient living and working environment. Therefore, the IoT has brought in a new era of machines that make our lives easier. See also: Chipless RFID; Cloud computing; Internet
