Digital Twin
A Digital Twin is like a virtual copy of a real machine, factory, or system that exists on a computer. Think of it as a sophisticated computer simulation that mirrors a physical object in real-time. Just like someone might practice on a flight simulator before flying a real plane, companies use Digital Twins to test, monitor, and improve their equipment and processes without risking the actual hardware. This technology helps companies predict problems before they happen, test changes safely, and make better decisions about their operations. You might also hear it called a "virtual twin," "digital replica," or "digital shadow."
