Which statement best distinguishes analogue data from digital data?

• A. Analogue data is continuous; digital data is discrete binary numbers
• B. Digital data is continuous
• C. Analogue data is stored digitally
• D. Digital data cannot be stored

Answer: (A)

Analogue data varies smoothly over time and can take an infinite number of values within a range, so it is continuous. Digital data, in contrast, uses separate, discrete values (typically binary 0 or 1) to represent information. That gap between continuous variation and discrete steps is the key distinction. A practical example is sound: a raw analogue waveform is continuous, while a digital recording stores sampled values that are quantized to a finite set of levels in binary form. The statement capturing analogue data as continuous and digital data as discrete binary numbers is the best way to express their fundamental difference.
