What is it? 

The Internet of Things (IoT) is the massive, invisible network of physical objects connected to the internet. By embedding microcontrollers and smart sensors into everyday items, businesses can gather massive amounts of real-time data from the physical world.    

How it changes the game: 

Instead of waiting for a human to report a problem, the objects report it themselves.  

Real-World Example:  

Think about the future of preventive healthcare and telemedicine. Instead of a patient waiting to feel sick before calling a doctor, they can wear smart, biometric sensors. These IoT devices constantly track the patient's vitals. If a heart rate or oxygen level drops below the healthy baseline, the sensor immediately sends an automated alert to a medical system, allowing for rapid, life-saving intervention before an emergency even happens.
