The Internet of Things, or IoT, refers to a network of physical devices that connect to the internet and communicate with each other. These devices can range from everyday items like smart home appliances to industrial machines. By using sensors and software, IoT enables these devices to collect and exchange data, making them smarter and more efficient. IoT has numerous applications, including home automation, healthcare monitoring, and smart cities. For example, a smart thermostat can learn your preferences and adjust the temperature automatically, while wearable devices can track your health metrics in real-time. This interconnectedness enhances convenience and improves decision-making across various sectors.
