Digital Twin for beginner

What is a Digital Twin?

• A physical model of a product used in testing laboratories.

• A real-time virtual representation of a physical system.

• A standalone simulation of a product with no real-world connection.

• A duplicate copy of a system used only for documentation purposes.

Which of the following is NOT a key component of a Digital Twin?

• Physical product in real space

• Virtual product in virtual space

• Data that connects the physical and virtual systems

• 
  A standalone software tool without physical connection

Who is credited with providing the first complete characterization of the Digital Twin concept?

• NASA
  

• Michael Grieves

• Lee et al.

• Rosen et al.

What was the primary industry where the concept of Digital Twin first emerged?

• Automotive
  

• Aerospace

• Healthcare

• Manufacturing

What is the primary purpose of a Digital Twin?

• To replace physical systems entirely.

• To provide a virtual environment for entertainment.

• To evaluate, predict, and optimize the performance of physical systems.

• To duplicate physical systems for archival purposes.

How does Industry 4.0 enhance Digital Twin systems?

• By eliminating the need for real-time data updates.
  

• By providing large amounts of real-time data for better operation and control.
  

• By making simulations static and unchangeable.
  

• By disconnecting virtual and physical systems.

Which of the following is NOT an example of a system that can use a Digital Twin?

• A fleet of vehicles
  

• A manufacturing line
  

• A mathematical calculator

• A power plant

What distinguishes Digital Twins from traditional simulation models?

• They use historical data only.

• They require real-time data updates from the physical system.

• They only operate on a single scale.

• They do not interact with physical systems.

What process describes the data flow between physical and virtual systems in a Digital Twin?

• Twinning
  

• Simulation

• Modeling

• Virtualization

According to NASA, which of the following features does a Digital Twin use?

• Multi-physics, multi-scale, and probabilistic simulations.

• Static data updates and real-time monitoring.

• Simple models without historical data.

• Only one physical property for analysis.
