What is a Pseudo Random Number Generator (PRNG)?

A Pseudo Random Number Generator (PRNG) is an algorithm used to generate a sequence of numbers that appear random but are actually determined by an initial value called the seed. PRNGs are not truly random because they rely on mathematical computations, making them deterministic and reproducible if the same seed is used.

PRNGs are commonly used in computer applications such as simulations, cryptography, gaming, and statistical sampling. While they are fast and efficient, they are not suitable for high-security purposes because their sequences can be predicted if the algorithm and seed are known.
