arpa net internet
ARPAnetInternet
  • Transition Period 1971-1983
  • Packet Switching developed and perfected
    • Instead of point-to-point persistent connections
    • Robust, fault-tolerant, efficient, survivable
  • Network of Networks realized on a large scale
    • The ability to connect different types of networks TCP/IP
early internet 1983 1989
Early Internet 1983-1989
  • No web browsers, no web pages at all…
  • Only…
    • Email
    • FTP (document and image sharing)
    • Early message board system (BB systems)

in 1989 came the www
In 1989 came the WWW
  • The concepts existed, but one man implemented the concepts and made them real…
  • WWW concepts
    • Hypertext concept – Documents can have links to other documents, just click the text
    • URL concept – Documents, computers, virtual mailboxes, networks can all have uniform identifier to help locate them
tim berners lee tbl
Tim Berners-Lee (TBL)
  • He invented the WWW in the sense that he put together a bunch of “good ideas” and implemented…
    • The first web browser
    • The first web server
  • In the process he proposed and developed
    • HTML
    • The URL concept
before the www finding stuff was hard
Before the WWW, finding stuff was hard
  • To find documents or data on the Internet you had to
    • Know numeric IP addresses to locate FTP servers
    • Login anonymously or with a user account
    • Know the folder hierarchy and file name of the document/data.
  • People would share this information via Email.
    • The idea of just browsing the Internet was silly, you just couldn’t do it.
    • If you didn’t have connections, you had no idea what was out there…
understanding the www
Understanding the WWW
  • HTTP instead of FTP
    • Web Browser instead of FTP client
    • Web Server instead of FTP server
  • URLs instead of numeric IP addresses
  • Clicking Hyperlink instead of navigating through folder hierarchies
  • Universal/Standard document formatting HTML instead of proprietary documents Word, doc, docx, pdf, etc.

Internet

  • Nuts and bolts

    • The WWW is a framework built “on top of” the Internet. The framework includes protocols for sharing data, standards for formatting data, and conventions for locating data. (The boat)
    • The Internet is really the “transport layer” of the WWW. (The river)
www matures 1989 1995
WWW Matures 1989-1995

  • 1993 The National Science Foundation (NSF) creates the InterNIC, which centralizes the control of URL and domain names
  • 1995 NSFnet(formally ARPAnet) becomes research only network
    • Internet traffic starts to get routed through a commercial backbone (operated by AT&T, Sprint, and others)
commercialization period 1995 2000
Commercialization Period 1995-2000

  • Microsoft Integrated IE into the Windows OS and it was often forced upon people as the default browser
    • Microsoft paid billions in lawsuit (EU mostly) but still won the war
