Question

Which of these is an advantage of digital storage of information over analog?
A. A copy of an analog file is never as good as its original.
B. Analog storage of information is continuous and captures a more pure sound.
C. Analog signals take up less bandwidth or storage space than digital.
D. Sound can be recorded either digitally or using analog techniques.

Answer 1

A.

Explanation: Digital storage allows exact (lossless) copies and is resilient to degradation via error detection/correction, so copies can match the original. B and C describe analog claims that are not advantages of digital, and D is just a factual statement, not an advantage.
