The Internet of Things (IoT) refers to the network of physical devices, vehicles, appliances, and other objects that are embedded with sensors, software, and connectivity, allowing them to collect and exchange data over the internet. This enables the creation of smart systems that can monitor and control various aspects of our environment, from traffic and weather to energy usage and home automation. IoT devices can communicate with each other and with central systems to optimize efficiency, automate tasks, and improve decision-making. The data collected from these devices can be analyzed to provide insights and improve performance, leading to a more connected and efficient world.
