Random Number Generator

In actuality, the majority of random numbersused in computers are pseudo-random that is to say they are generated in a predictable manner with an algorithm. This is fine for various reasons, but they may not be random in the way that you would expect when you're used to dice rolls and lottery drawings.

RANDOM.ORG is a website that provides real random numbersto anyone on the Internet. The randomness comes from atmospheric noise. This for a variety of purposes is better than the fake-random numberalgorithms usually used in computer applications. There are many people who use RANDOM.ORG to host drawings, lotteries and sweepstakes. They also drive online games, for applications in science and arts and music. It has been operating since 1998 and was founded by Dr Mads Haahr from the School of Computer Science and Statistics at Trinity College, Dublin in Ireland. The present day, RANDOM.ORG is operated by Randomness and Integrity Services Ltd.FREE services
