What is the correct order from most to least efficient method for passing data within an application?

The correct order from most to least efficient method for passing data within an application is based on how each method handles data in terms of performance, memory usage, and maintainability.

Wires are the most efficient method for passing data as they provide direct connections between nodes in a LabVIEW block diagram. This direct connection means that data can flow seamlessly without any overhead or delay, making it highly efficient in both real-time applications and for maintaining low memory usage.

Next in the order is the Feedback Node. It allows data to be carried over iterations of a loop without requiring separate memory allocation outside the data flow paradigm, but it is slightly less efficient than using wires directly since it does involve a small amount of overhead in managing the feedback loop.

Shift Registers are also efficient but involve more complexity than Feedback Nodes because they require additional management in terms of resetting and initializing the values stored. While they still provide a straightforward method of storing data from one iteration of a loop to the next, the performance can be slightly affected compared to Feedback Nodes due to contextual setup and maintenance.

Global Variables rank as the least efficient method for passing data because they introduce external references that can add a layer of complexity and overhead. Using global variables can lead to issues with data integrity, as they may
