Introduction & Overview

We meet one another, and I tell you what this class is going to be about.

August 20
History of the Web

It now seems hard to imagine a time before the Web, but it is less than a quarter-century old. Understanding why and how it was developed is key to understanding its current evolution.

To read before this class:

  1. History of the Web. Oxford Brookes University, 2002. PDF.

    A concise yet thorough history of the origins and development of the Web. Pay particular attention to Appendices C and D, in which Tim Berners-Lee outlines his proposal for the project that would become the Web.

  2. Berners-Lee, Tim. “Enquire Within upon Everything; Tangles, Links, and Webs; info.cern.ch.” In Weaving the Web. San Francisco: Harper, 1999. PDF.

    This optional but short excerpt from Tim Berners-Lee’s book explains in his own words how the Web got started.

August 25
Internet Architecture

The Web is built upon the Internet, so some basic knowledge of the Internet’s architecture is a prerequisite for understanding Web architecture.

To read before this class:

  1. Yanowitz, Jason. “Under the hood of the Internet: an overview of the TCP/IP protocol suite.” Crossroads 1, no. 1 (September 1994): 8–10. http://dx.doi.org/10.1145/197177.197182.

    A brief and accessible introduction to TCP/IP, the protocols used on the Internet.

  2. Kessler, Gary C. “An Overview of TCP/IP Protocols and the Internet”, 2010. http://www.garykessler.net/library/tcpip.html.

    This memo provides a broad overview of the Internet and TCP/IP, with an emphasis on history, terms, and concepts. It is meant as a brief guide and starting point, referring to many other sources for more detailed information.

  3. Leiner, Barry M, Vinton G Cerf, David D Clark, Robert E Kahn, Leonard Kleinrock, Daniel C Lynch, Jon Postel, Larry G Roberts, and Stephen Wolf. “A Brief History of the Internet.” arXiv:cs/9901011 (January 22, 1999). http://arxiv.org/abs/cs/9901011.

    Several founders of the Internet share their views of its origins and history. This history revolves around four distinct aspects: technological evolution, operations and management, social coordination, and commercialization.
