Which of the following best represents digital data?

Digital data is best represented by discrete values. This is because digital systems operate on distinct and separate values, which can be represented as binary data – typically in the form of 0s and 1s. In contrast to analog data, which is continuous and varies smoothly, digital data quantizes the information into specific intervals or steps, enabling clear and precise communication while minimizing issues such as interference and distortion.

Discrete values allow for easy manipulation, storage, and transmission of data without losing integrity, which is a key feature in digital communications and computing. Using discrete values ensures that the information can be reliably reconstructed and interpreted by electronic devices. This characteristic is foundational in various digital technologies, including computer systems, cellular communications, and digital audio and video formats.
