Switch A and B, select a gate, and observe the output with its truth table.

Prediction before clicking

The output is completely determined by the selected Boolean rule and the current inputs.

What the simulator is showing you

The output is completely determined by the selected Boolean rule and the current inputs.

Try to predict the next output before changing the input. A prediction is evidence that you understand the mechanism. If the result surprises you, trace the bit values or the stored state explicitly.

These experiments are simplified teaching models. The rules are intentional and inspectable, but they do not simulate transistor propagation delay, power consumption, or real processor pipeline details.
