Somehow reading through DxD again I managed to confuse myself and was hoping you guys could help me out.

What exactly is the difference between magic and demonic power? More specifically, between magic-circles and defensive barries made of demonic power. I think the anime inaccurately portrayed the use of defensive magic-circles and fucked up my thinking in this.
