How Does My Computer Work?

Have you ever wondered how computers really work? The basic idea is quite simple.  A computer can count up to two.  That’s right!  One, two.  Or, actually, zero, one. This can interpreted as yes/no or light on/light off.  And messages moving at a speed we can’t imagine are being sent to make words, pictures, pages….

This counting to two is called the binary system. That is, adding to the base two. (Our normal numbering system is base 10 – decimal system)

Here’s a video of a wooden adding machine which uses marbles for adding in binary. It is fabulous! And it will help you to understand how binary numbers work. Enjoy!
