Pseudorandom

A term that describes anything that appears to be characterized by randomness and unpredictability but has a known origin.

Pseudorandom is the term used to describe tangible or digital objects that have random elements or functions, even though this randomness is not authentic. The concept arises from random numbers which have no pattern whatsoever, and the spin-off of these numbers, pseudo-random numbers which also have no discernible pattern but can be traced back to a deliberate beginning or source.

The main difference between anything random and pseudorandom is that the latter can be repeated and has far more predictable outcomes than the former.
