As already dicussed in your other thread, another question that has nothing to do with LabVIEW.
If you want to get familiar with DAQ hardware and software, I would recomend you go to the Getting Started with DAQmx tutorial. Since you can easily add simulated DAQ devices with Measurement & Automation Explorer, you can try many of the shipping examples or run through the different tutorials. This answer (and other hardware related) would then be pretty apparent.
