Video conference terminology

Do you know your video conferencing terminology?

I’m not sure if it’s just me, but I always feel a bit lost when speaking with a different generation than mine or dealing with a new group or particular profession. What are they saying? I know when I’m having a conversation with a non-court reporting professional about court reporting, I can tell the point that I need to speak more in layman terms. The glossed over eyes are a big clue. I get it.
