Which statement describes a disadvantage of analogue data?

• A. It can deteriorate when copied or transmitted due to signal corruption
• B. It can never be stored
• C. It does not require any physical storage
• D. It is always higher quality than digital data

Answer: (A)

Analogue data is a continuous signal, so it picks up noise and interference easily. When you copy or transmit it, even small amounts of distortion become part of the signal, and with each transfer the degradation can get worse. That is why deterioration due to signal corruption is a clear drawback of analogue data. Analogue data can be stored on physical media like tapes, records, or film, so statements claiming it cannot be stored or that it doesn’t require storage aren’t correct. Also, saying analogue is always higher quality isn’t accurate: digital data can be preserved exactly and protected from noise with proper techniques, while analogue quality depends on the hardware and can degrade over time.
