Many of these devices are referred to as "smart" devices: smartphones, smart homes (Internet-capable thermostats, appliances, and so on), smart televisions, and many more devices. Through Bluetooth, Wi-Fi, and other means of wireless communication, users of smart devices are able to control them and oftentimes connect them functionally with other smart devices. Connections to the Internet allow these devices to track usage habits, provide helpful recommendations (e.g., a refrigerator that sends an alert to a homeowner's smartphone when a visit to the grocery store is needed), and generally offer users a more interactive and feature-rich experience.
