Is random really random?

Question

what really i have problem with is as computer works on OS which is basically a set of programs and does only what the program tells to do so how can we tell a computer (as it doesnt have any own creativity) to give random output

Answer 1

They're usually not truly random, but are called pseudo-random because they generate a number sequence that appears random. This is done with some interesting mathematical formulas. One of the most common is the Linear Congruential Generator.
//Good Question ^_^

Answer 2

We can do better than plain Linear Congruential Generators (LCG) though, by reading hardware noise (how hot is you cpu, and lots of other stuff), and use that as a seed of our LCG for high-quality, close-to-random numbers.

Answer 3

thanks

Answer 4

and this logic works same on any device that has OS or calculates randomly
