A random number generator is a computational or physical device designed to generate a sequence of random numbers. For example, a random number generator could create the winning numbers for a lottery.
Random number generators are important because they can be used to create unpredictable outcomes for games, simulations, and other applications. They are also used in cryptography to generate keys, which are essential for keeping data secure. The first modern random number generator was developed by John von Neumann in 1951.
