Rapidly changing field: –vacuum tube - transistor - IC - VLSI (see section ) –doubling every years: memory capacity processor speed (Due to advances in technology and organization) •Things you‘ll be learning: –how computers work, a basic foundation –how to analyze their performance (or how not to!) –issues affecting modern processors (caches, pipelines) •Why learn this stuff? –you want to call yourself a ―computer scientist‖ –you want to build software people use (need performance) –you need to make a purchasing decision or offer ―expert‖ advice.
