Frequently Asked Questions
What is a random number generator?
A random number generator (RNG) is a tool that produces numbers in a specified range with no predictable pattern. Common uses include:
- Games and simulations
- Statistical sampling
- Cryptography and security
- Scientific research
- Lottery and gambling applications
What's the difference between true and pseudo-random numbers?
There are two main types of random numbers:
- True Random Numbers: Generated from physical processes (quantum events, atmospheric noise)
- Pseudo-Random Numbers: Generated by mathematical algorithms
For most applications, cryptographically secure pseudo-random numbers are sufficient.
What are common applications of random numbers?
Random numbers are used in many fields:
- Gaming: Dice rolls, card shuffling, loot drops
- Security: Password generation, encryption keys
- Statistics: Random sampling, simulation
- Education: Problem generation, student selection
- Research: Experimental design, testing
- Entertainment: Contests, giveaways
