Digital vs. Analog: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Digital data is binary, represented as discrete numbers. Analog data is continuous, represented in physical quantities.
Key Differences
Digital technology encodes information as binary data (0s and 1s), suitable for computers and digital devices. Analog technology, in contrast, represents information through continuous physical quantities, like voltage or waves.
