And microprocessors don't just think for computersyou might find a processor in many other everyday items like your telephone or car. To help you understand how the microprocessor does its job, you will go step by step through a simple task on the chip. For the purpose of this demonstration, you will add two numbers together while watching the microprocessor do its magic. You will complete this task in four easy steps and you may review each step as many times as you want.
