The Internet of Things (IoT) refers to the connection of devices (other than traditional computers and smartphones) to the internet, allowing them to send and receive data. These devices can include everything from everyday objects like thermostats and refrigerators to industrial equipment like tractors and airplanes. The goal of IoT is to allow devices to share data and work together to increase efficiency, reduce human intervention, and improve safety. Some examples of how IoT is being used include smart homes, connected cars, and wearable fitness trackers.
