Are you an expert in DNS?

-
1)Why does the internet use IP addresses?
             - The internet uses IP addresses in order to identify which website is which, and who it belongs to.

2)Why don't we need to know IP addresses?
            - Because sometimes, one IP address stays the same for one website, and it never changes. Henceforth IP address stay the same as it originally was for some websites, but not all.

3)Why do we need a Domain Name System?
            - Because we need to know certain tags for websites, when they cant be accessed by how they originally are.

4)Why don't we all maintain our own DNS?
            - Because having our own DNS isn't always necessary or needed all the time.

5)Is there one big DNS for the entire internet?
            - In my opinion, I don't think so because, the internet is just to big of a source for it to have just one DNS for all the the content and information for the internet.

6)How do you think all these DNS servers are maintained?
           - I think that all of these DNS servers are maintained by different systems that contain IP addresses or TCP/IP similar to one another.

7)What is one vuinerability of DNS and how is that vuinerability attacked?
           - One vuinerability of DNS is to know how the domain name system works. That vuinerability is attacked when the IP address has a overflow, and can't be accessed at once.

8)What are the implications of a attack on a DNS server (or servers)-how does this affect your life?
          - The implications of an attack on a DNS server is that  it cancels that access of website(s) and systems. It affects my life because I used the internet everyday, and I need  access to the internet to do work.

Blown to Bits: Chapter 2, 5, 7, 8 Summary

-
Chapter 2 The second chapter of Blown to Bits, entitled  Naked in the Sunlight  brings forth the alarming fact that in a world of bits, none of one’s information can be protected.    The author opens up the chapter with a comparison to George Orwell’s novel  1984 , where the characters are always being watched by a government force called Big Brother.    In the novel, the ruling party has complete surveillance over all the people, and the author compares this to modern day London.    The author cites the Subway bombers of 2005 to prove his point.    During the time of the bombings, London was under heightened security, and by using the footage from surveillance cameras, they had no problem getting images of the bombers and their trip before detonating the bombs.    Finally the author draws the conclusion that “1984 is here, and we like it”. Chapter 5 In chapter five of Blown to Bits, the author explores the complex wor...

Blown To Bits: Chapter 3-Ghosts in the Machine

In chapter 3 of "Blown to Bits",  pages 91-92 discuss how certain objects were used before, and differentiates on how it's used and changed in today's society. One example that the chapter mentions is how music used to be stored on a compact disk known as a CD, but it's changed now in the present.In the chapter it says, " At the time the CD format was adopted as a standard, decompression circuitry for CD players would have been too costly for use in homes and automobiles, so music could not be recorded in compressed form. The magic of Apple’s iPod is not just the huge capacity and tiny physical size of its disk, it is the power of the processing chip that renders the stored model as music.  The birth of new technologies presage the death of old technologies. Digital cameras killed the silver halide film industry; analog television sets will soon be gone; phonograph records gave way to cassette tapes, which in turn gave way to compact disks, which are themselv...
