Explanation
DSL (Digital Subscriber Line) transmits data over standard household copper telephone lines (POTS - Plain Old Telephone Service). It uses frequencies above the voice range, allowing simultaneous voice and data on the same wire. Cable internet uses coaxial TV cable (A). Fiber optic is a separate technology (FTTH/FTTP).
