The Internet of Things (IoT) is when everyday devices—like fans, refrigerators, or lights—connect to the internet and become “smart.”
For example, a smart bulb can be switched on with your phone, or a smart watch can track your health and send data online.

IoT is all around us today: in homes, schools, farms, hospitals, and cities. It makes life easier, but it also brings some challenges such as privacy risks, cost, and the need for reliable internet.
