What is meant by a random number generator?

AllCalculator.net's A random generator is a number chosen from a pool of limited or unlimited numbers in a no discernible pattern for prediction. The numbers are almost independent, which may follow a specific distribution. A random number generator is a device that generates one or many numbers within a defined scope. Hardware-based random-number generators can use a coin for flipping, a dice, or many other devices. 

Computer-based random number generators are pseudo-random generators that are not truly random. Random numbers generated are for many applications; they should not be used for cryptographic purposes. Random numbers are based on physical phenomena such as thermal noise, atmospheric noise and quantum phenomenon.

How a random number generator calculator does works?

AllCalculator.net's Random number generator calculators use mathematical algorithms to get a sequence of numbers without any predictability. The algorithms are designed based on randomness properties such as;

• The uniform distribution of numbers
• The independence of numbers
• The unpredictability of numbers

The idea behind random number generators is to start with a seed value to initialize the generator. Use a set of mathematical operations to produce a sequence of numbers.

Is there any logic behind the random number generator?

Random number generation is a process by which means of a random number generator, a sequence of numbers or symbols that cannot be reasonably predicted, then by random chance is generated. The particular outcomes have certain patterns which are detectable but unpredictable to foresight. True random generators generate random numbers, wherein each generation is a function of the current value.
