  4. YouTube Example

  5. Google Apps Express • James Beswick “Google Apps Express” • Barrie Sosinsky “Cloud Computing Bible”

  6. Main Frame Computers • IBM • Amdahl • CDC • Univac • Sperry-Rand

  7. Time Sharing • Dumb Terminals • Hard Wired • Security was physical (fire suppression) • Used Punched Cards • The Cloud was the ‘Owner’ of the computer data

  8. Mini Computers • PDP, VAX, SyFA • Hard Wired • Local Control • Proprietary Terminals • Telephone Connections

  9. Storage & Back-Up • Physically Move Tapes • No way to (easily) transfer data • Used 8” Floppies

  10. Emergence of Personal Computers • ‘Kits’ (Altair 8800, 1975) • Commodore, TI, Radio Shack • DOS versions • Apple 1977 • IBM compatible 1981 • PC ‘Man of the Year’ 1983 • Cloud was a floppy: 5.25” & 3.5” (sneaker net) • Cloud was file transfer (300, 600 & 1,200 bps)

  11. PCs became ‘smart terminals’ • Still hard wired • Now had viruses on floppies Software was ‘proprietary’ • Exchange of data almost impossible • Each PC had its own printer/plotter • Fonts were not interchangeable • Crude networks possible

  12. Email, Bulletin Boards & Newsgroups emerge • Transfer rates 600, 1200, 2400, 9600 bps • Protocols: Gopher, Archie, Veronica, Jughead • Emails: Delphi, AOL, CompuServe, Prodigy (incompatible) • Viruses more prevalent

  13. PDF Created to Transfer Documents • Guarantee that documents ‘look’ similar • Desktop Publishing flourished • Multiple font types prevailed

  14. A Brief History of the Internet • ( http://www.walthowe.com/navnet/history.html) • 1969 ARPANET • 1972Telenet • 1983 TCP/IP • 1989 Tim Berners-Lee describes WWW • 1993 Mosaic graphical browser • 1998 Windows 98 solidified Microsoft’s dominance

  15. The Original Prevalence of ‘free’ software • Linux • Open Source • Netscape browser

  16. Data Storage & Back-ups • Floppies, CDs, DVDs & external hard drives • File transfer to a third party • Security, Viability & Reliability issues • All transfers were user initiated

  17. Emergence of a Second Computer • Laptop, either personal or work • Need to access ‘main’ computer • Remote login software solutions (phone) • Security: keep out the bad guys

  18. Emergence of ‘WIRELESS’

  19. Emergence of Mobile Computing • PDAs & Blackberrys • iPhones & Smart Phones • Internet kiosks & cafes • Wi-Fi hotspots • Always connected devices
