Smart devices are electronic gadgets that connect to the internet and can communicate with each other. They often have built-in sensors and software that allow them to perform tasks automatically or be controlled remotely. Examples of smart devices include smartphones, smart speakers, and smart thermostats. These devices can enhance convenience, improve energy efficiency, and provide users with real-time information. Many smart devices are part of the Internet of Things (IoT), a network of interconnected devices that share data and work together. This technology enables users to control their devices through apps or voice commands, making everyday tasks easier. For instance, a smart home system can adjust lighting and temperature based on user preferences.
