A digital system is a set of devices for transmitting, processing, or storing digital signals that use discrete (discontinuous) values.

In contrast, non-digital (or analog) systems use a continuous range of values ​​to represent information . Although digital representations are discrete, the information represented can be discrete, such as numbers, letters, or icons, or continuous, such as sounds, images, or other measurements of continuous systems.

The word digital originates from the Latin word digitus (meaning finger), since fingers were used for discrete counting.

Its use is most common in computing and electronics, especially where real-world information is converted into binary numerical form, as in digital sound or digital photography. Category: Digital Technology
