Definition

Describing numbers or processes that appear random but are generated by a specific, predictable method.

Example

The algorithm produces pseudorandom numbers that are used in simulations.

Conversation

Have you heard about how computers generate pseudorandom numbers?

Yeah, it's pretty interesting how they use algorithms to do that.

Right? I read that they can pass tests for randomness even though they're not truly random.

Exactly, it's fascinating how they can simulate randomness so effectively.

Root Explanation

Pseudorandom → It is formed from "pseudo-" (from Greek "pseudes", meaning false) and "random" (from Latin "random", meaning having no specific pattern). The word "pseudorandom" describes something that appears to be random but is actually generated by a deterministic process.

Memory Tip

Think of 'false' ('pseudo-') randomness — that's why pseudorandom means it seems random but is actually not.
