According toWikipedia, “a smart device is an electronic device, generally connected to other devices or networks via different wireless protocols such as Bluetooth, NFC, WiFi, 3G, etc., that can operate to some extent interactively and autonomously.”
Another way to define it is a version of a regular device that is connected wirelessly. For example, a traditional deadbolt lock needs to be manually turned open and closed either with your hand or by a key, while a smart lock can be controlled by an app on your phone over Bluetooth or remotely over your home network.
While smart locks are not something you encounter in most homes yet, one of the more popular smart devices is the Nest Thermostat. It has the capability to learn from the settings you manually apply to it. It also allows you to interact with it remotely by using an app on your smart phone. Soon virtually every device in your home will have a smart alternative.
