Modem Converts Digital to Analog | Generated by AI
Question: What does a modem (MODEM) primarily convert between digital data and ___?
Answer:
A modem (modulator-demodulator) primarily converts between digital data and analog signals.
- Modulation (调制): The modem takes digital data (0s and 1s) from a computer and converts it into analog signals that can be transmitted over telephone lines or other analog communication channels.
- Demodulation (解调): The receiving modem converts the incoming analog signals back into digital data that the computer can understand.
Therefore, the correct answer to fill in the blank is: analog signals (模拟信号).
The reference answer “模拟信号（或模拟数据）” is also acceptable, but in precise technical terms, we usually say analog signals rather than “analog data”, because what is being transmitted over traditional telephone lines is an analog waveform (continuous signal), not discrete “analog data”.
Final recommended fill-in: 模拟信号
