This is what I am not able to read anywhere:
*I actually do not know if I already having modules installed? How do
I test it?
*What is modules used for?
*Is modules (already) included the image?
*Why is there a separate file called modules? Why not include it in the image?
*Is modules a standard Linux "thing"?

I am asking as a novice. I have not encountered information about modules at:
