The Internet of Things (IoT) refers to the network of physical devices connected to the internet and capable of collecting and exchanging data. These devices range from everyday objects to industrial machinery and can communicate wirelessly or through wired connections. The IoT enables communication between devices and the cloud, allowing users to monitor and manage them remotely. Devices can range from wearables like fitness trackers to smart appliances, security systems, medical devices, and industrial sensors. By combining sensors, connectivity, and data analytics, the IoT provides automation and real-time insights, transforming various sectors like healthcare, manufacturing, agriculture, transportation, and more.
