A smart device is a gadget that can connect to the internet, talk to other devices, and can do things that regular devices can't do. For example, a smart TV can access the internet and show you shows or movies from different streaming services. A smart thermostat can sense when someone is in the room and adjust the temperature accordingly. A smart speaker can listen and understand what you say, allowing you to ask questions and control your home. Smart devices make it easier and faster to do things and can make our lives much easier!
