HTTP and Abstraction Reflection

Day 2: HTTP  and Abstraction
          Important vocabulary and concepts
              Abstraction: what is it?
              Server and clients: What are they, how do they interact with each                    other?
          Use of some Developer Tools
              Paired partner activity to discover and observe HTTP traffic
  1. What surprised you about the HTTP traffic you observed?
  2. What does it mean to say that high-level layers of the Internet use low-level layers “abstractly”?
  3. What other examples of abstraction have we seen in this course? Hint: Unit 1 is basically all about abstraction.

HTTP Reflection:
  1. I am surprised that the HTTP traffic was either lower or higher depending on how popular I thought the website was. There was also times that would display how fast they were loading.
  2. This means that the high-level layers used the low-level layers’ functionality without actually knowing how to get the lower layers’ functions. HTTP doesn’t need to worry about the layers except its own text protocol.
  3. Another example of abstraction we have seen before is the HTTP making full use of the ASCII character set without actually referring to how these characters are encoded. Like many other examples, HTTP doesn’t need to know the ASCII works as it can take care of that using its own protocol. (abstraction)

Reflections from Blown to Bits Ch. 3 (Homework- 9/28/17)

Read Blown to Bits (www.bitsbook.com), Chapter 3 , Ghosts in the Machine, pp. 80-88 (Representation, Reality, and Illusion), then answer the following questions: You can find this under forms and docs/Blown to Bits How does highlighting in a PDF doc work? What are the computational ideas utilized? Continue the exploration of HTML by determining how you would complete today’s activity in HTML. Further compare your own protocol with HTML. Reflections from Blown to Bits Chapter 3: Highlighting in a PDF docs works by using a Highlight tool that will send bits over to the letters and alter the binary. The binary is changed so that when the bits processes through, the letters will be the same but highlighted in a color instead. Between my own protocol and today’s activity, they look pretty similar since they are in the same HTML format. My own protocol was a little less precise about fully doing it in HTML due to being new at the protocol.

Blown to Bits Appendix/Ch.3 Reflection (Homework- 10/11/17)

Day 3: Packets and redundancy Homework due Wednesday, Oct 11: Blown to Bits (www.bitsbook.com), Appendix - The Internet as System and Spirit, pp. 301-309, “The Internet as a Communication System,” then answer the following question: It is interesting to think about the foresight (or luck?) that caused initial Internet designers to choose a packet-switched network as the basis for the Internet. What do you think, foresight or luck? Blown to Bits (www.bitsbook.com), Chapter 3 - Ghosts in the Machine, pp. 91-92, “Data Formats as Public Property,” then answer the following question: What do you think the Internet would be like today if different companies’ network protocols were still competing for adoption for the Internet, instead of TCP being the de facto standard? Blown to Bits Ch.3 Reflection- (by Josh Lim) I believe it is foresight because they were not fully aware on their issues at the time. The designers from the experiments would have trouble understan...
