Interesting views on what makes computers tick are described in Woz biography on how he invented the Apple computer, the first personal computer, or home computer. I find important on how he was able to think about signals, components that process signals, and software as flexible ways of combining components. Also, one of the breakthroughs that made computers possible was the invention of dynamic memories. On wikipedia and google picture search, it is possible to see some of Woz' hand written tables on 0's and 1's and pictures on what components need to be combined to get some magical effects.
Furthermore an interesting list of readings on how computer concepts shape our ways of how we perceive the world around us:
