Introduction
             Babbage- 1800's invention had input, storage, processing, and output
             ENIAC- needed to flip switches and connect wires
             Types of Storage-ROM, RAM, Hard Drive, and Floppy
             Processors-are made up of many switches
             Digital Information
             Bits-smallest unit of info (in ASCII: American Standard Code for Information Interchange)
             Pixels-480 x 640 lines resolution (much more at present)
             Microprocessors
             -used in car brakes and in remote controls
             -they are programmed when they are manufactured
             -its vocabulary is binary code (1&0 s or on/off)
             -to be a software engineer you must think logically and breakdown the big ideas into smaller ones
             -Fetch: gets the code by retrieving it from memory
             Decode: finds out what the code does
             Execute: does the math and what the instructions tell it to do
             -78 microprocessors in Audi cars by 2005
             Creating Chips
             -chips are made in totally clean room
             -mass-designers translate ideas into physical designs
             -clean room is 1000 times cleaner than surgical room
             -are assembled by computer controlled robotics
             -Assembly Process: 1. deposit layer 2. Photo resist 3.create a mask over the material 4. harden it with a special light 5. the excess material is etched away
