  1. CS101 Three Important Concepts

  2. Concept 1: Your Computer is Stupid! However, it is getting smarter, and it talks to computers that are getting smarter! Cognitive Computing

  3. Concept 2: To be a computer a device must do four things. • Input Information • Input Devices • Process Information • Processor • Output Information • Output Devices • Store Information • Storage Devices

  4. Here is is… • https://www.youtube.com/watch?v=0anIyVGeWOI

  5. Concept 3: Information needs to be in form of zeros and ones for a computer to process it. • Information must be in the form of zeros and ones because the processor is make up of switches. • Intel and Advanced Micro Devices are the two types of processors found in most personal computers • Switches in processor have two states: On and Off • Off = 0 On = 1

  6. Four Generation of Processors When they figure out how to make processors in a different way that makes the processors faster, cheaper, smaller, and more reliable a new generation of processors is born.

  7. First Generation 1939 –1956 • Vacuum tubes

  8. Second Generation 1956 –1963 • Transistors

  9. Third Generation 1964 – 1971 • Integrated Circuit

  10. Forth Generation = 1971 - present • Silicon Microprocessor

  11. Fifth Generation? • http://www.engadget.com/2015/07/26/single-molecule-transistor/#continued • Quantum Computing • How Quantum Computing Works

  12. Under 70 years from.. • 18,000 switches in a room, failure every day, 120,000 watts, 3 computers in the world To • Billions of switches on multicore chips, failures are rare, 10 - 25 watts, hundreds of processors in your daily life.
