From the Document: "The Internet of Things (IoT) is a system of interrelated devices that are connected to a network and/or to each other, exchanging data without necessarily requiring human-to-machine interaction. In other words, IoT is a collection of electronic devices that can share information among themselves. Examples include smart factories, smart home devices, medical monitoring devices, wearable fitness trackers, smart city infrastructures, and vehicular telematics. Potential issues for Congress include regulation, digital privacy, and data security as discussed below."
