Digital Twin

A Digital Twin is like having a virtual clone of a physical object or system that allows you to monitor, analyze, and optimize its performance in real-time. Imagine a factory where every machine has a digital counterpart that tracks its operation, predicts maintenance needs, and helps improve efficiency. Digital twins bridge the physical and digital worlds, providing valuable insights and enabling proactive management.

A Digital Twin is a digital replica of a physical entity, such as a machine, building, process, or system. It captures real-time data from sensors and other sources to create a dynamic, continuously updated model that mirrors the physical counterpart. This virtual representation helps in understanding and optimizing the performance of the physical object or system.
