Wow. I wish I had had this book back when I was taking my first Computer Architecture course in college! It carries you along from the very fundamentals of both codes (like braille) and electric circuits in the telegraph days all the way to the web in a way that even a layperson could understand, with plenty of verbal and diagrammatic explanation. It does at points get pretty deep into the weeds but I really appreciated the author's efforts to provide such an exhaustive dive into how computers work (and I regained much of my awe at these machines we take so for granted nowadays).

The final chapter was a rushed overview of the web and felt almost like an afterthought after the thoroughness of the rest of the book, but I didn't ding the author on it--there's plenty of great writing about how the web works that you can read elsewhere. Read this book to gain a deeper understanding and appreciation for the birth of the modern digital age. Thank you Charles Petzold!
