Among the listed internet connection types, 'Fiber to the curb' (FTTC) generally provides the fastest speeds. FTTC involves running fiber-optic cables close to the curbs near homes or businesses, with the remaining connection to the premises being made through traditional coaxial or ethernet cabling. This provides higher speeds compared to traditional DSL (Digital Subscriber Line) or cellular connections.
