Angels vs demons

i know its basic magick 101 but could someone clarify the difference between angels and demons. i know ones not evil or good because that would be up to the interpreter, but what planes do each come from? How do they operate differently? Why would one use the other over another? etc.

This has to due with prefrence. Look into each spirit you want to work with. Find the one you feel more comfortable with. Research is everything.

I’ve stated everything there,I believe.
