Elena gasped. She ran back to the book.

The first chapter was not a command. It was an invitation. It began not with a 1 or a 0, but with a story—of a simple light switch. Floyd explained that a switch wasn't just "on" or "off"; it was a state . A decision. Elena flicked the lamp on her desk. Click. Light. Click. Dark. fundamentos de sistemas digitales thomas l. floyd

She understood the smooth sweep of a second hand, the continuous flow of electricity in an old radio. But logic gates? Flip-flops? They were meaningless symbols.
