Is it possible to generate truly random numbers using a computer?

WebDec 13, 2016 · Random numbers are generated from random unpredictable processes like thermal or atmospheric noises, cosmic radiations, etc. We need special hardware or sensors which can measure such processes and there could be a program which can produce a number from the input of random events. Computers can generate truly random numbers by observing some outside data, like mouse movements or fan noise, which is not predictable, and creating data from it. This is known as entropy. Other times, they generate “pseudorandom” numbers by using an algorithm so the results appear random, even though … See more Random numbers have been used for many thousands of years.

WebJust changing this number by one will cause a completely different sequence of random numbers to be generated. So let's call the previous number (or the seed when generating the first one) P. Then our next random number, let's call it R, is. R = a * P + c (mod m). So we have a couple more letters here, a, c and m.
