Spread spectrum refers to any technique where a narrowband signal is deliberately spread to occupy a larger bandwidth.
Frequency-hopping is an example of a spread spectrum technique; they're not different things. Direct-sequence spread spectrum (which is what I think you're describing) is also a spread spectrum technique.
There are also other techniques; the most popular one is probably the chirp spread spectrum as used in LoRA.
