Modulator-Demodulator corresponds to which acronym?

• A. MODEM
• B. MARS
• C. NWP
• D. JANAP

Answer: (A)

The main idea here is that the term MODEM literally reflects its function: it is a device that Modulates digital data into an analog signal for transmission and Demodulates the received analog signal back into digital data. This bidirectional conversion lets computers communicate over traditional phone lines and other analog media. The other acronyms refer to different concepts outside this data-communication role, so they don’t describe a device that handles modulation and demodulation. In short, MODEM is the one that embodies Modulator-Demodulator.
