Charles Petzold’s writes in his book, Code: The Hidden Language of Computer Hardware and Software,

In a very creative style, Charles Petzold walks readers through a maze of discoveries and innovations which ultimately culminate into contemporary computers and coding. The pages are dense in technical explanations and so in order to grasp the big concepts of how we evolved into coding, I made the following images…
