The Internet of Things (IoT) connects everyday devices by embedding sensors and software that facilitate communication and data exchange over the internet. This connectivity allows devices—from appliances to wearables—to share information, interact with each other, and provide valuable insights to users. For example, a smart thermostat can learn user preferences and adjust heating or cooling accordingly. IoT enables automation and remote control of devices, improving efficiency and convenience in daily life. Its applications range from smart homes and healthcare to industrial and agricultural sectors, revolutionizing how we interact with technology.
