The word "digital" comes from the Latin word "digitalis", which means "belonging or relative to the fingers". In contrast to "analog" (continuous), the digital technique or technology represents information with numerical values.

Computers, for example, represent information with binary digits. Each bit can only have two states, which we can represent as 0 and 1. Two bits can have 4 values; four bits, 16 values; eight bits, 256 values, and so on.

Since the digital representation reproduces a value in the form of an encoded number, the range of values ​​represented can be very wide, although it is limited by the amount of bits used.

Astronomy and astronautics have driven digital technology since its birth and its use is increasingly widespread. Almost all of the instruments used today are fully digital or have digital components.
