Smart city

Smart cities are cities that use technology to make things easier and better. For example, they might use sensors, which are like tiny computers that measure things like the temperature or air quality. They can also use cameras to watch over the city, so the police can keep an eye out for any bad activities. Smart cities also use technology to help people get around more easily, like with ride sharing apps or public transportation. Finally, they can use information to make decisions and plan for the future of the city.
