How do computers determine random numbers
WebThere are a number of ways to detect or sense "random" information that can be used as a seed, or better, an actual random number. There may be other methods, also, that have yet to be developed. Just because a computer can't be programmed to do something currently, this does not mean the computer is unable to perform it. 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. Whether it’s flipping a coin or rolling a dice, the goal is to leave the end result up to random chance.
