[GIS] Official term for latitude longitude coordinate system

coordinate systemreferences

May I know what is the correct specific term for latitude longitude coordinate system?

With "Geographic Coordinate", it seems to be a general term for every other system?

A standard term is geodetic coordinate system. However, the market leader in GIS software tends to invent new terminology with each new release of its flagship system, and by virtue of gaps in fundamental training by most of its users (or just plain enthusiasm for new words), this terminology quickly gets adopted by the majority. For example, "Geographic coordinate system" was newly introduced with ArcGIS 8 about ten years ago but AFAIK it was not in common use before then.
