In Erlang, how is the use of registered processes different from global variables in a traditional language?

Question

It seems to me that this is one and the same thing, just registered registered processes are masked by the terminology “actors”.

Update:

Since then, I have seen a mistake in my way of thinking. I assume that since I'm new to Erlang, I used actors in places where they didn't belong at all (is there any name for the template?)
