Pseudorandom numbers are sequences of numbers that appear to be random but are actually generated by a deterministic algorithm. This means that if you start the algorithm with the same initial value, known as a seed, it will always produce the exact same sequence of numbers. True randomness, on the other hand, is unpredictable and cannot be reproduced.

The primary purpose of pseudorandom number generators (PRNGs) is to create sequences that exhibit statistical properties similar to those of truly random numbers. This makes them useful in a wide range of applications, including computer simulations, statistical sampling, cryptography, and video games. For instance, in simulations, pseudorandom numbers can mimic real-world random events. In cryptography, they are essential for generating keys and one-time pads.

Despite their deterministic nature, well-designed PRNGs are capable of producing sequences that pass many statistical tests for randomness. However, it's important to note that they are not truly random. In contexts where genuine unpredictability is paramount, such as in high-security cryptographic applications, true random number generators (TRNGs) that rely on physical phenomena like thermal noise are preferred. The choice between pseudorandom and true random numbers depends entirely on the specific requirements of the application.
