LabVIEW Quiz

1. What does VI stand for?

   Visible Items
   Visible Information
   Virtual Instruments

2. What is the purpose of a LLB-file?

    To make an application which can be run on any computer without having LabVIEW installed
   To save the VIs more quickly
   To store the VIs of an application as one single file, for easy distribution of the application 

3. How can you (as a developer) hide the VI-diagram for a user?

   You can not do it.
   You can check the proper checkbox for it during saving (File / Save with Options / Application).
   You must check the proper checkbox for it via the menu Edit / VI Properties.

4. How many global variables can be stored in one single Global VI?

   Only one for each different global variable type 
   1
   There is no limit

5. Which is the preferred method of exchanging data between different while-loops in a diagram?

   Using local variables
   Using global variables
   Draw a signal line across the borders of the loops in the usual way

6. See this VI: vi1. How many times does the for-loop run?

   19
   20 
   21

7. See this VI: vi1. What is the value of the i-variable after the VI has stopped?

   19
   20
   21

8. See this VI: vi1. Which kind of data is avaliable at the terminal point of the signal line in the VI-diagram?

   A scalar (one single data value)
   An array of numerical data
   A cluster of numerical data

9. What is a cluster?

   A multi-variable containing different variables having various data types
   A multi-variable containing different variables having equal data types
   Just a displaying effect (to make a number of controls or indicators) appear as one unit 

10. Suppose you will have a realtime plot (being continuously updated) on the front panel. Which kind of plotting indicator would you use?

    X-Y-graph
    Chart
    t-Y-graph 

11. Which operations can not be used in Formula Node?

    Linear algebraic operations
    If-statements 
    Switch-structures 

12. Which of the following has no workspace in which the variables are stored as long as the VI runs?

    Matlab Node
    Formula Node 
    HiQ Node

13. Which of the following expressions are correct if used in Formula Node: 

    y=a+b 
    y=a+b;
    y=a_1+b;

14. What can you use a shift-register for?

    Store former values of a variable
    Store former VIs
    Automatically repair the "register" on your car 

15. Which of the following graphics formats can not be used on a front panel?

    BMP
    WMF
    JPG

16. Which of the following document formats is not available when creating  documentation automatically via the File / Print-menu?

    Word
    Rtf
    Html

17. What does it mean that FieldPoint is a distributed I/O-system?

    That it is distributed freely 
    That LabVIEW-code is run distributedly (on the FieldPoint-system) 
    That the I/O-channels are distributed - away from the computer

18. What can you use the MAX-program for?

    To calculate max- (and min-) values of a measurement signal
    To maximize the performance of a VI
    To configure I/O-cards by National Instruments 

19. Which limitations exist for using DataSocket to distribute data over a network?

    It can be used only on an intranet.
    It can be used on the Internet.
    It can be used only between to PCs in a computing room on a campus

20. What determines the program order of execution of code in LabVIEW? 

    The time when you entered the code
    It goes from left to right.
    The data flow
