What is a digital twin?

1. A physical replica of a machine

2. A virtual representation of an object updated with real-time data

3. A model used only for estimation purposes

4. An outdated manufacturing process

The correct answer is: A virtual representation of an object updated with real-time data

A digital twin is defined as a virtual representation of an object that is updated with real-time data. This concept enables organizations to simulate, predict, and optimize the performance of a physical asset or system by mirroring its behavior and characteristics in a digital environment. This real-time aspect is critical as it allows for monitoring and analysis that can lead to better decision-making and improved operational efficiency. By integrating data from sensors and other sources, a digital twin can provide insights into the status of the actual object, aiding in predictive maintenance, performance management, and scenario analysis. The other choices do not accurately capture the concept of a digital twin. A physical replica does not include the dynamic and interactive features of a digital representation. A model used solely for estimation lacks the real-time updates and feedback necessary for effective monitoring and analysis, while describing a digital twin as an outdated manufacturing process does not relate to its current relevance and application in modern industries.
