HTTP and Abstraction: Blown to Bits Response

Blown to Bits, Appendix:
The layers of protocols used in network communication is an example of abstraction. Can you give other examples of abstraction in everyday life?
-Abstraction is used for many things in our everyday lives. For example, abstraction can help us in problem solving, in imagination, and in thoughtfulness.
When you browse to a web page, maybe with some animated advertisements embedded on it, describe in detail what happens behind the scenes to display that page on your browser.
-The DNS of the website finds the IP Address of the computer, and then the website groups TCP packets together and sends them to the website. This is how the ad is displayed.
Blown to Bits, Chapter 3:
Question about abstraction: Discuss how not knowing some basics of how a software tool or computer works, and the abstractions they use, could lead to bad outcomes.

-This could lead to many problems. For example, if the program is not used as it is intended to, problems and errors could arise. Also, the human error factor is increased massively, since they do not know fully what they are doing.

Reflection on Blown to Bits Chapter 1

Koan 1: It’s All Just Bits Koan 2: Perfection Is Normal Koan 6: Nothing Goes Away Koan 7: Bits Move Faster Than Thought Pick one of the above koans and address the following questions: Argue if you agree that it is a "truth" and if it will always be a "truth." How does this koan intersect with your life as a student? I think that Koan 6: Nothing Goes Away is a truth, and will always be a truth. This is because, with computers, there are so many bits and so much space to store them that even if you try to delete or remove something from a computer, it will never truly be gone. When you delete something on a computer, it is not truly “deleted” per se but instead overwired with new data. The original data can still be recovered, and seen easily. Data can be kept forever, unless there are explicit policies to get rid of it. Because of this, I think that there is no true way to remove things completely from databases or computers. This koan intersects with my l...

Ghost in the Machine reflection (Blown to Bits p. 73-88)

Ghosts in the Machine, pp. 73-80 (What You See Is Not What the Computer Knows), then answer the following questions: Give an example of your own when just knowing what a computer did wasn’t sufficient - you really needed to know how and why it was doing what it was doing as well. -An example of when this happened to me was when I was building my own computer, and I needed to start it and install the operating system onto it. This process was difficult, and I needed knowledge about computers to complete it. Talk about file metadata and how it “fingerprints” a file. Include a discussion of file metadata benefits and challenges. -Metadata includes information such as the name, description, the owner of the computer that created the document, the last time the document was edited, and the last time the document was edited. This information can be useful. However, leaked authorship information can have consequences. If you plagiarize someone else’s work, then use it as your own, the me...

Homework Day 3: Computing Innovations

Select an innovation. It can be anything.Describe the positive and negative impacts it has had on the world. (A satisfactory answer reflects awareness and analysis of the effects on populations beyond the students’ immediately locale.) One innovation that changed the way we go about our days today is the mobile phone. This invention is innovative because something that nearly everybody has today is a mobile phone. Several positive effects that the mobile phone has had on today’s society include convenience, as sophisticated mobile phones contain ways to keep your personal information close at hand, and social aspects, as you can communicate with your friends via your mobile phone.  While there are positives to the mobile phone, there are also negatives as well. The mobile phone can be distracting, and all the features it has can stop you from being productive and diligent while the phone is within reach. Another negative of the mobile phone is the expenses associated with it. ...
