Blown to bits chapter 3

1.The layers of protocols used in network communication is an example of abstraction. Can you give other examples of abstraction in everyday life? 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.2.Discuss how not knowing some basics of how a software tool or computer works, and the abstractions they use, could lead to bad outcomes.


 Answer: When u have limited knowledge or no knowledge on a software you don't know what people can do with that software. Such as redact  information form government document like in the case of caliper. The US government and online form of their report which was redacted meaning censored or covered. The redacted version was then uncensored and released. this happened because the people who redacted the report didn't realize what could be done with tool open to the internet.  Programs suck as adobe acrobat could have easily encrypted the data to keep the uncensored version being released, but they didn't know those basic it came to a bad outcome.This can easily happen to our daily life. lets say an old person is using Photoshop or in design. if they didn't know how to use it they wont make any work out of it. they need to know the basic of Photoshop and in design to start making anything descent. If they didn't know what file type to use or what tools does what they could end up with complete mess as a final result.

        New technology makes artificial intelligence more private and portable This article was mainly about how a new AI  was invented that would allow devices to operate independent of the internet. Good news is the new deep-learning AI software produced with that technology is compact enough to fit on mobile computer chips for use in everything from smartphones to industrial robots. Meaning that it can be really easy to access it and its really useful. It can lead to much lower data processing and transmission costs, greater privacy and use in areas where existing technology is impractical due to expense or other factors. The way it functions is that it mimics the human brain by processing data through layers and layers of artificial neurons, typically requires considerable computational power, memory and energy to function. Also the AI can adopt  and change itself to keep functioning each time computational power and memory are taken away. Meaning it...

         Net Neutrality repeal!  This post is from current news and form my knowledge. I am concerned so I thought it was important to write about it.  Foxnews ,  The guradian The FCC(federal communication commissions) repealed Net neutrality that was placed by Obama.

Now you have  each and every website and no one can block you or block content but Now that net neutrality got repealed your access to those information might be reduced or blocked and the government or hosting site have the power. So now people wont be able to write freely on the internet or use it free. government will be watching and it is not good! The internet was successful and used widely because its free and i believe that if net neutrality gets taken out, The use of the internet will be effected in a wide range.
