When a novice doesn't know the exit instruction, he will randomly input some instructions as an attempt, and the input instructions will become random numbers because they are randomly tried by the novice.

Real random numbers are generated by physical phenomena, such as coin toss, dice, wheels, noise generated by using electronic components, nuclear fission and so on. This kind of random number generator is called physical random number generator, but the disadvantage is that the technical requirements are relatively high.

The method of computer generating true random numbers is to obtain the uncertainty of cpu frequency and temperature, and count the number of operations in a period of time, which will produce different values, system time errors and sound card noise floor every time.
