About Simulario

Simulario is a free site of learning paths for systems and software engineering. Every lesson is built around a simulation you can control turn by turn.

How it teaches

Every lesson follows the same order: predict, run and explain. First you read just enough theory to reason, then you anticipate what the system will do, watch it happen step by step, and finally compare your prediction with the result. Getting the prediction wrong is part of the method: it shows exactly which idea needs adjusting.

Tokens

Everything that moves in a simulation (a process, a thread, a memory page) is a token with its own shape and color, so you can tell them apart even if you cannot see the colors.
