What technology enables the transport of computer data over analog telephone local loops?

The technology that enables the transport of computer data over analog telephone local loops is best represented by telephone modems. These modems convert digital data from computers into analog signals that can be transmitted over the traditional telephone lines and then convert incoming analog signals back into digital data for the computer.

While the other options offer various forms of data transmission, they do not utilize analog telephone local loops in the same manner. Digital Subscriber Line (DSL) is a technology that runs over the same copper wiring but uses a different method than standard modems, allowing for higher speeds and separate channels for data and voice. Fiber optic cables transmit data using light signals instead of electrical signals, and they are a different medium entirely. Wireless routers provide a means to connect devices wirelessly to a network, not over telephone lines, but through radio signals. Thus, telephone modems specifically serve the function of handling the analog-to-digital conversion needed for transmitting data over traditional phone lines.
