How Does the Computer Work?
Jeffrey Toobin: How does the computer work, Jeff? Well, I won't go into everything that makes a computer work. But let's talk about the basic building blocks, a transistor. And even more basic than that, a semiconductor material,. silicon is a semiconductor. At low temperature, there are no free charges, no free electrons that can move around. So when you talk about electricity, you're talking about predominantly electrons moving to establish electrical currents.
