How Does a Microprocessor Work?
NOTE: Being a techie and an engineer, I’m often asked questions about how things work. These types of questions are the best, because as you might imagine, engineering types are generally obsessed with how things work. So, I have created a new category on my site here entitled “How Does it Work?”
The first post in this new category is the answer to a question that a friend just asked me the other day: How does a microprocessor actually work?
Everyone nowadays is familiar with microprocessors. Everything now uses a processor of some kind: computers, MP3 players, cell phones, washing machines, food processors, and even some electric toothbrushes!
One question I get asked a lot is: how do these processors actually work? Everyone knows that there is a thing called a microchip, and that it has transistors. But how do you go from a bunch of ones and zeros to a video playing in the web browser on your cell phone? I hope to explain here in very simple terms how a microprocessor works without getting too technical – and therefore too boring!
