Random Number Generator (RNG)

A Random Number Generator (RNG) is a system that produces numbers without any predictable pattern, ensuring each number is different and unbiased. In digital devices, RNGs often use complex algorithms or physical processes, like measuring electronic noise, to generate these unpredictable values. They are essential in applications like cryptography, gaming, and simulations where unpredictability and fairness are crucial. While "true" RNGs rely on physical phenomena for randomness, many digital systems use pseudorandom number generators—algorithm-based methods that mimic randomness but are deterministic if the initial seed is known.
