#### Number

A random number generator (RNG) is a algorithm or mathematical function that produces a sequence of random numbers. The numbers generated by an RNG are typically used for tasks such as generating random encryption keys, simulating random events in computer models, and generating random numbers for statistical sampling.

Random number generators are classified into two types: pseudo-random and true random.

A pseudo-random number generator (PRNG) is a computer programme that generates random numbers. It's similar to shaking a bag of numbers and randomly selecting one, but the computer can do it much faster and repeat the same sequence of numbers if we tell it to. It's not as random as rolling a dice, but it's close enough for many of the fun and important things we do on computers.

A true random number generator is a computer programme that generates a truly random number that cannot be predicted or controlled. It's like spinning a wheel with no pattern or rolling a dice with no bias, so each time you roll it, you get a different number.

A cryptographic pseudo-random number generator is a computer programme that generates numbers that appear to be random but are actually generated using a set of instructions or a formula. It's similar to a robot that can roll a dice and generate a random number, but it does so using a special code. Imagine it as a special machine that makes toy cars, and every time you press the button, it creates a different car, but it actually follows a blueprint to make it. It's still cool, but not entirely unpredictable.

## What is a Random Number Generator?

A Random Number Generator is a mathematical construct that generates a number that is taken from a limited or unlimited distribution and outputs it. The two main types of random number generators are pseudo random number generators and true random number generators.

## What is the difference between Psuedo Random Number and True Random Number?

True random number generators rely on unpredictable physical phenomena, such as atmospheric noise, radio static, and the timing of radioactive decay, to produce their output. Pseudo-random number generators use mathematical algorithms to produce a stream of numbers that are initially unpredictable but become predictable as a result of progressive repetition (the sequence generated by a PRNG can be described by a relatively small number of rules).

## How to Generate Random Numbers?

Here are the simple steps to generate random Numbers:

• You can enter the minumum length number under the “Min” cell.
• You can enter the maximum length number under the “Max” cell.
• Click on the “Random Number Generator” button.
• The results will be displayed under the “Number” cell.

## Where are random numbers useful?

Random numbers are used in many applications, including cryptography, to generate secure keys and encryption codes to protect sensitive data. They are also used in gaming to generate random results in dice rolls, card shuffling, and slot machines. Random numbers can be used in simulations and modelling to simulate real-world scenarios and to generate random inputs to test and validate models. In statistics and data analysis, random numbers are also used to generate random samples from a population and to perform statistical tests. They are used in artificial intelligence and machine learning to introduce randomness into algorithms and to randomise the initial weights in neural networks.

Random numbers are also an important tool in computer science, mathematics, and many other fields, allowing for the solution of a wide range of problems. Random numbers have an infinite number of applications and fields; they are widely used in research and development to validate various concepts, test and evaluate new ideas, and develop new methodologies.
