WebThere are two common methods for generating random numbers from a computer: Pseudo-Random Number Generators (PRNGs) and True Random Number Generators (TRNGs). To generate PRNGs, a computer uses a seed number and an algorithm to generate numbers that seem to be random, but are actually predictable. Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but unpredictable to foresight.
