The service has existed since 1998 and was built.Similar considerations apply to generating other non-uniform distributions such as Rayleigh and Poisson.An example would be the trng9803 14 hardware random number generator, which uses an entropy measurement as a hardware test, and then post-processes the random sequence with a shift register stream cipher."Various techniques used in connection with random digits" (PDF).8 Some security-related computer software requires the user to make a lengthy series of mouse movements or keyboard inputs to create sufficient entropy needed to generate random keys or to initialize pseudorandom number generators.K2 A sequence of numbers which is indistinguishable from 'true random' numbers according to specified statistical tests.This method produces high quality output through a long period.Such sequences have a definite pattern that fills in gaps evenly, qualitatively speaking; a truly random sequence may, and usually does, leave larger gaps.This is fine for many purposes, but it may not be random in the way you expect if you're used to dice rolls and lottery drawings.Some applications which appear at first sight to be suitable for randomization are in fact not quite so simple.

Activities and demonstrations edit The following sites make available Random Number samples: The socr resource pages contain a number of hands-on interactive activities and demonstrations of random number generation using Java applets.
