MODEM stands for which term?

• A. Modulator-Demodulator
• B. Message Encoding Digital Modem
• C. Modulation Demodulation System
• D. Mainframe Data Modem

Answer: (A)

MODEM is short for Modulator-Demodulator. The name highlights its two main roles: converting digital data into an analog signal for transmission over communication lines (modulation) and converting the received analog signal back into digital data (demodulation). This dual function enables data to travel over media that carry analog signals, such as traditional telephone lines, and then be read as digital information at the other end. The other options don’t match the established terminology: they either describe a function in a way that isn’t how the term was coined or refer to a use-case rather than the original naming.
