Answer:
In the case of online training, communication between the speaker and the participant is live using the Internet. During the training, each participant can ask questions via chat at any time. You need a reliable, fast Internet connection and a headset. A dongle is no longer required, as the licensing of the new program generation (RFEM 6, RSTAB 9, RSECTION) is online.
If you want to simultaneously model on your computer during the training, you should use two monitors. This way, you can see your program interface and the video at the same time.
