What is the function of a random number generator?

[Julio88]

A random number generator is a software algorithm or a hardware device that produces a sequence of numbers that doesn't follow any recognizable pattern or sequence. The purpose of a random number generator is to generate a sequence of numbers that can be used in various applications, such as cryptography, scientific simulations, and computer games.The random number generator can be either a true random number generator or a pseudo-random number generator. True random number generators generate random numbers based on some unpredictable physical process, such as atmospheric noise, thermal noise, or radioactive decay. Pseudo-random number generators, on the other hand, use a mathematical algorithm to generate a sequence of numbers that appears to be random but is actually deterministic - it can be reproduced if you know the seed value.
The function of a random number generator is to provide a source of randomness that can be used in various applications where unpredictability is important. The quality of a random number generator depends on its ability to produce a sequence of numbers that pass statistical tests for randomness, and on its resistance to cryptographic attacks.

Random number generators are designed to generate random numbers. It means that it should be computationally impossible to predict the following number in the sequence given the sequence of previously created numbers. They must produce random numbers effectively,

Overall, the function of an RNG is to provide a reliable source of randomness and unpredictability, ensuring fairness, security, and statistical validity in various applications. The specific implementation and quality of an RNG may vary depending on the requirements and industry standards of the application in which it is used
