In the past we published a lot of information about how things are working. Many of it was only partial, some was intentionally wrong for different reasons (security, trigger etc...). In this forum we now try to slowly bring the things together as they really are. We will define new terms and redefine old ones. And maybe we also will nullify old terms. The topics of this forum do not nullify all old information, but we will try to set them in order and context. But also many my become simply outdated.
