In this phone, there are nearly 100 million transistors, in this computer there's over a billion. The transistor is in virtually every electronic device we use: TV's, radios, Tamagotchis. But how does it work? Well the basic principle is actually incredibly simple. It works just like this switch, so it controls the flow of electric current. It can be off, so you could call that the zero state or it could be on, the one state. And this is how all of our information is now stored and processed, in zeros and ones, little bits of electric current. But unlike this switch, a transistor doesn't have any moving parts. And it also doesn't require a human controller. Furthermore, it can be switched on and off much more quickly than I can flick this switch. And finally, and most importantly it is incredibly tiny. Well this is all thanks to the miracle of semiconductors or rather I should say the s
