To use the analog telephone system for sending digital data, you must also use a modem. A modem converts digital data into analog signals for transmission and converts received signals back to digital data.

To use the analog telephone system for sending digital data, you must also use a modem. Here’s how it works:

Digital Data Conversion: Digital data, which consists of binary ones and zeros, needs to be converted into analog signals. A modem (short for modulator-demodulator) accomplishes this task. It modulates digital data into analog signals for transmission over telephone lines and demodulates the received analog signals back into digital data at the receiving end.

Analog Signal Transmission: Analog phones transmit data over a continuous range of frequencies. The modem converts binary ones and zeros into analog frequency tones that can be reliably sent over these frequencies.

Noise Reduction: Digital systems, including those using modems, handle noise better than pure analog systems. Any error that a small amount of noise introduces can be effectively detected and corrected.

For example, when sending computer data over an analog phone line, a sending modem translates the digital data into analog signals. At the receiving end, another modem converts the analog signals back into digital data for the computer to process.
