You clicked this switch at the start. Back then, it was simply a control.

Now you can see the layers beneath it.

At the bottom, transistors give the computer two physical states. We describe them as 0 and 1. Groups of those bits can represent instructions and information. The CPU, GPU, RAM, and storage pass those patterns around while doing different jobs.

One switch still cannot do much alone.

Connect switches so the state of one affects another, and simple choices begin to form rules.

That is where logic begins.
