Which statement describes an advantage of analogue data?

• A. Digital storage generally requires less physical space
• B. It cannot deteriorate when copied
• C. It stores continuous signals without quantization
• D. It cannot be copied

Answer: (C)

Analogue data keeps a signal in a continuous form, so there is no quantization of amplitude. This means the stored value can match the original waveform more closely, preserving details that digital systems would have to approximate with discrete steps. That continuous, non-quantized representation is the main reason it’s seen as an advantage. In practice, this fidelity is balanced by trade-offs: analogue signals are more vulnerable to noise and distortion, and copies can deteriorate over time. The other statements aren’t advantages because digital storage isn’t inherently smaller in physical space, analogue copies can degrade, and analogue data can indeed be copied (often with some loss in quality).
