Cultural Tip
The structure "C'est quoi…?" is very common in everyday spoken French, but it is considered colloquial. In written or formal French, prefer the inverted form "Qu'est‑ce que…?". Also note that DSL is being replaced by fiber‑optic connections in many French households, so younger speakers might be less familiar with the term.
