Easier to design. Exact values of voltage or current are not important, only the range (HIGH or LOW) in which they fall.
Information storage is easy.
Accuracy and precision are greater.
Operations can be programmed. Analog systems can also be programmed, but the available operations variety and complexity is severely limited.
Digital circuits are less affected by noise, as long as the noise is not large enough to prevent us from distinguishing HIGH from LOW (we discuss this in detail in an advanced digital tutorial section).
More digital circuitry can be fabricated on IC chips.
