• The World Wide Web (WWW)
  • Inventor: Sir Timothy John Berners-Lee (1989)
  • WWW not invented from scratch
    • Assembled by adapting and borrowing from six existing technologies and concepts
      1. Internet/TCP/IP, networking, protocols: ftp, gopher, telnet
      2. Client-server architecture
      3. Addresses, domain names, TCP ports – access methods – URI – URN -> URLs
      4. SGML  – Markup -> HTML
      5. Hypertext – non-linear documents – hyperlinks -> HTTP
      6. Email/MIME (multipurpose internet mail extensions) – connectionless/stateless sessions
         1. Document header
         2. Document body

  • IETF, Internet Society
    • RFCs
      • https://en.wikipedia.org/wiki/List_of_RFCs
  • Connectionless protocol (e.g., Ethernet, IP, UDP, etc)
    • IP is not designed to be reliable and is a best effort delivery protocol
    • UDP provides data integrity via a checksum but does not guarantee delivery
  • Connection oriented protocol (TCP)
    • TCP provides both data integrity and delivery guarantee by retransmitting until the receiver acknowledges the reception of the packet

• IP addresses:   IPv4 (32 bit), IPv6 (128 bits)
• TCP and UDP port numbers (16 bits)
  • https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
• Another layered model of the Internet

Review the following three Wikipedia articles:

• Internet
• Internet protocol suite
• World Wide Web

For each article, suggest an edit or addition that would improve the quality, clarity, completeness, or accuracy of the article. The improvement for each article should be “coded” using Wikipedia’s markup language.

Do not save your changes to Wikipedia! You can use “Show preview” to see the effect or your edit, but after using the editor to “create and copy” your edit for each article, select “Cancel“.

Mail homework to gmadey@nd.edu and qzhi@nd.edu by end of Friday, with Subject line: CSE 40613 – your NetID – HW2

Mail should include for each of the three article improvements:

1. The full page & anchor link to the section you are editing.
2. Your suggested edit in Wikipedia markup; Italicize your edits.
