A framework is mostly a bunch of component interfaces, but it does not implement those components. The framework does implement some glue code to help tie the framework together, and it provides some utility implementation for things that you’re likely to need.
A game engine implements all of the components defined in the framework… or at least all of the components that the game engine developer feels is required in order to implement his game engine. In some cases, an engine might not need physics or networking, etc, and so the game engine developer may choose to leave these components out of his engine.
Does that answer it?
