RNG (Random Number Generator)

A Random Number Generator (RNG) is a system that produces a sequence of numbers without any predictable pattern. It can be software-based, using complex algorithms, or hardware-based, relying on physical processes like atmospheric noise. RNGs are essential for applications needing unpredictability, such as secure encryption, gaming, or simulations. True randomness is challenging to achieve, so many RNGs generate "pseudo-random" numbers that appear random but are produced through deterministic methods. Overall, RNGs help introduce unpredictability and fairness where needed.
