  1. History of Computers (Cont’d)

  2. 2ndGeneration Computers • Transistor replaced vacuum tube • Solid-state device invented at Bell Labs • Smaller, faster, less heat • Magnetic core memories • Floating-point hardware support

  3. 2ndGeneration Computers • High-level languages used • ALGOL, COBOL and FORTRAN • System software: compilers, subroutine libraries, batch processing • Digital Equipment Corporation (DEC) • PDP-1

  4. 2nd Generation Computers • IBM 7094: 32K memory, 185 instructions, 500 KHz, FP

  5. 3rdGeneration Computers • Integrated Circuits (IC’s) • Integrate components into a silicon chip (transistors, resistors, conductors, etc.) • Silicon is semiconductor • Transform silicon through chemical process • Conductions • Insulators • Both

  6. 3rdGeneration Computers • Time-sharing • IBM 360 family • Broke backwards compatibility • IBM dominant computer vendor • DEC PDP-8 • Minicomputer • $16k • Fit on a lab bench

  7. 3rd Generation Computers • Gordon Moore (Intel) • Moore’s Law Doubling of transistors / area / year at same cost

  8. 3rdGeneration Computers

  9. 4thGeneration Computers • Intel • 4004: first microprocessor (4-bit) (‘71) • 8008: 8-bit • 8080: first GP uproc. • 8086: 16-bit • 80386: 32-bit (’85)

  10. 5thGeneration Computers • VLSI • Intel • 80486: 1.2 million • Pentium II: 7.5 • Pentium 4: 42 • Core 2 Duo: 167 • Core 2 Quad: 820 • …

  11. The Now Generation • SOCs • Smart phone • Tablets • And… Wearables

  12. Now Generation

  13. Now Generation • Apple A7 die

  14. Now Generation • Samsung Galaxy Note 4

  15. iPhone 6 • Leaks and conjecture: http://www.macrumors.com/roundup/iphone-6/ • Truth? • We’ll find out soon…http://www.apple.com/live/?cid=wwa-us-kwg-features-com
