Question: 1 / 400

What is one disadvantage of using Global Variables in LabVIEW?

They are easy to access from anywhere in the application

They can lead to data integrity issues

One significant disadvantage of using Global Variables in LabVIEW is the potential for data integrity issues. Global Variables can be accessed and modified from multiple locations within an application, which introduces a risk of race conditions and unintended data modifications. When different parts of the code interact with the same global variable simultaneously, it can lead to unpredictable behavior or corrupt data, making it difficult to ensure consistent and reliable application performance. Managing the state of global variables can become challenging, especially in complex applications where many different processes may be reading from or writing to the same variable at the same time. This concern contributes to why the use of Global Variables should be approached with caution, especially in larger, more complex systems where data consistency is paramount.
