"Turbojet and turbofan engine designs have helped by increasing bypass ratios,"

Isn't that basically the differentiation between a turbojet and a turbofan? Aren't they essentially the same, except the turbofan has a higher bypass ratio, so most of the thrust comes from the fan part, not the jet part?

Asking because I'm sure a few Reg readers will know for certain.
