Which term describes analogue data?

Which term describes analogue data?

• A. Data that is physically represented
• B. Binary
• C. Discrete digital values
• D. A combination of numbers 1 or 0

Answer: (A)

Analogue data is carried by continuous physical quantities that can vary smoothly over a range, such as a continuously changing voltage or light level. This means the information isn’t limited to fixed steps like in digital representations. The description “data that is physically represented” fits this idea because it captures the notion of a signal that exists as a continuous physical quantity carrying information, rather than as discrete binary states. The other options point to digital concepts—binary, discrete digital values, or a mix of 1s and 0s—which do not describe analogue data.
