The Internet of Things (IoT) refers to the interconnected network of physical devices that are embedded with sensors, software, and other technologies to communicate and exchange data over the internet. IoT devices include smart home gadgets like thermostats, lights, and security cameras, as well as industrial equipment and healthcare monitors. These devices collect and share data in real time, enabling automation, remote monitoring, and control. IoT has applications in various sectors, including agriculture, manufacturing, transportation, and healthcare, driving innovation and efficiency. However, the widespread use of IoT also raises concerns about security, privacy, and data management.
