Quizplus · Accepted Answer

DSL (Digital Subscriber Line) technology enables high-speed internet connections over standard copper telephone lines. It works by sending digital data through the unused frequencies in the telephone line, allowing users to access the internet while still being able to make voice calls on the same line. RS-232 and EIA-232F are older serial communication standards used for connecting devices like modems and printers to computers. FireWire, also known as IEEE 1394, is a high-speed data transfer technology used for connecting devices like cameras and external hard drives to computers. None of these technologies involve transmitting data over standard telephone lines. Therefore, the best choice for the given question is A) DSL.
