Digital Twin
A digital twin is a digital representation of a specific physical asset, process, or system that is maintained with relevant data so it can support monitoring, analysis, simulation, or decisions about its real counterpart.

Remember it this wayA digital twin is a maintained model tied to one real counterpart.
In plain language
The twin is more than a static drawing. It represents selected properties and states of something real and is updated through data, observations, or operational records.
Why it matters
A twin can support planning and prediction, but decisions are only as sound as the model scope, data quality, update process, and match between the representation and reality.
Example
A factory maintains a digital representation of a production line using sensor and maintenance data to test scheduling and failure scenarios.
Common misconception
A digital twin is not a perfect copy of reality. It is a purpose-built model that omits details and can become stale.
