Magic is magic, you'll come to find (if you stay on this site for awhile) that pretty much everyone has their own idea of what magic is. Mostly people have their own gods/goddesses that they believe in and worship.
However Wicca is not a type of magic. Nor is paganism.
The different names really don't matter they all mean the same thing.
As for the different types of magic...there is logicaly only one type of magic, everything else such as "summoning and spells and envocations"...etc are all things that people use with "magic" to do.
Black/white dark/light magic doesn't exist magic has no color.
But those are just my basic beliefs on magic, for the most part people all have their own. You can google it and maybe try to find out some information there, but dont base everything you know off of what people tell you, try to find things out for yourself.
