  • There are many algorithms (an algorithm is a a finite set of well-defined instructions for accomplishing some task) for generating random numbers. Some use the time as a seed (the base number of which all the rest of the random numbers are generated), others use other numbers. Typically, they are deterministic in a computer. That means that if you start with the same seed, you will get random numbers, but they will always come in the same order. This is known as a pseudo-random number generator. Of course, if you can generate random numbers, you can then use them to randomize anything such as the songs in your playlist.
  • There is no such thing as computer generated random numbers, only a sequence that is too long to recognize in our lifetimes. That is why encryption and security measures need to be updated frequently, as new exploits of current systems are detected.
