Random number theory explores mathematical methods for generating sequences of numbers that appear random, focusing on properties like independence and uniform distribution, with applications in fields like cryptography, simulation, and statistics.
Here's a more detailed explanation: The study of generating and testing sequences of numbers that exhibit characteristics of randomness, such as independence and uniform distribution. In practice, computers cannot generate truly random numbers. Instead, they use algorithms to produce sequences that appear random, known as pseudo-random numbers.
Applications for using random numers include:
Cryptography: Generating encryption keys and other security-related data.
Simulation and Modeling: Simulating complex systems and phenomena where randomness plays a role.
Statistical Sampling: Selecting random samples from larger datasets.
Games and Gambling: Generating random outcomes in games and lotteries.

That's why Cloudflare uses a wall of lava lamps on camera to generate truly random numbers.
ReplyDelete"Random" numbers in computing are probably best described as "quasi-random" or "random enough". They're usually based on a seed like the computer's internal clock at the moment the random number generator is called, altho' the seed can be anything the programmer wants it to be (usually something the user has no control over).
