Question

what is the fundamental reason that digital signals are so reliable for recording information? they use a simple system of 0s and 1s to represent information. they can only travel over very short distances. they are recorded using complex wave patterns. they are difficult to store on hard drives.

Explanation:

Digital signals rely on a binary system (0s and 1s) which is robust to noise and degradation. Unlike analog signals, the discrete states of 0 and 1 are easy to detect and correct, making digital signals highly reliable for recording information. The other options are incorrect: digital signals can travel long distances, they do not use complex wave patterns (that is analog), and they are easy to store on hard drives.

Answer:

A. They use a simple system of 0s and 1s to represent information.
