Pseudorandomness

Pseudorandomness refers to sequences or values that appear random but are generated by deterministic processes, such as algorithms. While true randomness comes from natural or unpredictable sources, pseudorandom numbers are produced by computer programs that use mathematical formulas to generate sequences that seem unpredictable and evenly distributed. They are essential in computing for simulations, encryption, and gaming because they mimic true randomness, even though they are ultimately reproducible if the starting point, or seed, is known. This balance allows for repeatability in processes while maintaining the appearance of unpredictability.
