1. Why are there two windows?

Once you open LabVIEW, there will be two windows that will appear.  The front panel is what the user of you program will interact with when they are running it.  Any type of user interface should go here.             The other window is where you will create your program.  All of LabVIEW programs use icon  to represent different functions.  Each of these icon have the inputs on the left and the outputs on the right. Linking the input of one to the output of another is as easy as drawing a wire between the two terminals.

 

2. How do you transfer data from one icon to another?

LabVIEW uses wires instead of variables. Connecting wires from the output of one icon to the  input of another icon is the same as passing a parameter  to a function in C++.  Using wires instead of text allows the program to easily follow the flow of data around his program.

3.  What is an Indicator?

Indicator's are used to display data on the screen that can be viewed by the user of your program.   Indicators in LabVIEW include:  Meter Digital Displays Gauges Graphs etc.

4.  What is a Control ?

Control's give the user of your program a way to  input data.  They can also be binary switchs that contol  different aspects of your program.  Controls in LabVIEW include: On-Off Switchs Dials  Digital Inputs etc.
