Question

Digital information is converted and transmitted in certain numbers that create a pattern. Analog data is transmitted in continuous waves. Old records contain analog data but can be converted to digital recordings. Which of these statements best describes how digital data compares to analog data?
A.
Digital data transmits signals more slowly than analog can.
B.
Digital data takes more space to store than analog does.
C.
Digital data can be stored for a longer period of time than analog can.
D.
Digital data records more unwanted background noise than analog does.

Answer 1

C. Digital data can be stored for a longer period of time than analog can.

Explanation: digital recordings are discrete and can be copied and transmitted without accumulating the quality loss and noise that analog signals suffer. Analog media degrade and accumulate noise over time; digital copies remain identical to the original.
