The document provides a history of the development of the Internet from its origins in the 1950s through modern times. It discusses early research networks like ARPANET, the development of packet switching, email, and TCP/IP. Major milestones included the first connections between computers in the 1960s, the introduction of email in the late 1960s/early 1970s, and the commercialization of the World Wide Web in the mid-1990s. The document traces the evolution of personal computing, social media platforms, and trends like the rise of Web 2.0 and today's challenges in areas like open versus proprietary technologies.

1. The History of the Internet
Kinda
#SMPASOCIAL
Dr. Nikki Usher

2. DARPA:
Sputnik: 1957

3. Computers were….
Sigma -7

4. Revolutionary ideas
• Computers could be PROBLEM SOLVING
• Computers could perform more than one task
• (Batch sharing)…. (computer punch card
below)

5. Major developments
• The idea of “time sharing”
• The idea of man-computer symbosis

6. Early bits of importance
• What would they share?
• Different software for every host computer

7. Even crazier- and more fundamental
1962: JCR Licklider at MIT – world-wide
computer network where once computer linked
to another, with anyone who could connect to
anyone else, anywhere….

8. Decentralization of nodes
Redundant networks
No central node*

9. ARPANET!!!!! (1962-66ish)

10. Packet-Switching (~1964/5/6)

11. First time talkers
-1965: TX-2 Computer at MIT talks to Q-32
Mainframe at RAND in LA
-Insert your favorite overlapping node/network
of UCLA/UTAH/STANFORD/UCSB
- Phone lines? Radio lines? Need better wires!!!

12. HOST-IMP (late 1960s)

13. EMAIL: 1968/1972
• An accident
• HUGE
• THERE WAS NO PROTOCOL. AT ALL.

14. TCP/IP: OPEN ARCHITECHTURE
SMTP; FTP; HTTP
DATA-divides into packets, puts back
together, checks if they are ok
(IP) – virtual address; packets called
datagrams
Ethernet: gets the packets and
sends/receives them

15. You don’t need an IMP, or a HOST

16. Moments in Personal Computing
• 1975: Altair 8800 commercially available PC
• 1976: Apple Computer founded
• 1978: First Mass-Marketed personal computer,
Apple II
• 1984: Apple Macintosh Launched

18. 1979:Usenet

19. 1981/1983: Ethernet/LAN

20. Standardization
• .com, .edu, .gov, .net, .org, .mil
• Domain name system (user@x.com)
• ARPANET begins to die

21. 1988: IRC, BBS

22. 1990: Arpanet dies, WWW lives
HTML
URL
LINKS

23. 1991: Gopher

24. 1993: Mosaic

25. WEB COMMERCIALIZED 1995
(DELPHI- 1992)
AOL, Prodigy, Compuserv

27. First Blog
• A COLLEGE STUDENT NAMED JUSTIN HALL IS
KNOWN AS ONE OF THE FIRST BLOGGERS IN
THE HISTORY OF THE INTERNETS!

28. 1995: Banner Year
• Yahoo
• Windows 95
• Amazon
• Ebay
• Java (programming language)
• Internet explorer

29. 1998: Bill Gates Eats the World

32. Socialish (OpenDiary/LiveJournal):
1998/1999

33. 2000s

34. MAS SOCIAL: FRIENDSTER

35. Myspace

36. WEB 2.0
• FACEBOOK…..
• Dr. Usher --- User 4,507 (slow to join…..)

37. Web 3.0?
• Semantic Web
• Platform agnostic?
• Proprietary v. open?
• HTML5
• Challenges of today’s programming
