Converting numbers from base 2 to base 10:
1. 1011 = 11
2. 101010 = 42
3. 11111 = 31
4. 10010 = 18
Converting numbers from base 10 to base 2:
1. 31 = 11111
2. 51 = 110011
3. 7 = 111
4. 103 = 1100111
How long will it take to download a 100MB file on each of the following connections:
1. a modem at 56KB/second
1KB/s = .125 KB/s = 56 KB/s = 7 KB/s = 100,000 KB/7KB/s = 3.97 H
2. DSL at 5 megabits/second
1MB/s = .125 MB/s = 5 MB/s = .625 MB/s = 100 MB/.625MB/s = 2.66 Min
3. high-speed connection at 10 Megabits/second
1MB/s = .125 MB/s = 10 MB/s = 1.25 MB/s = 100 MB/1.25MB/s = 80 Sec
If an internet connection an upload 3 megabits/second, and an MP3 is 60 Megabytes, how many MP3s can you upload in an hour?
3 MB/s = .325 MB/s = x/.375 MB/s * 3600 Seconds = 1350 MB / 60 MB = 22.5 Mp3s

Net Neutrality
One point lurking conspicuously under debates on net neutrality is whether or not the current system of the internet should be changed. Currently, all information on the internet is passed between computers with the same priority level, whether the information is a silly e-mail, or a scanned college diploma. Because of this, new sites just beginning potentially could turn into something largely known and popular in a very short time period, like YouTube. People who oppose net neutrality wish to assess priority levels of various transfers and give speed advantage to some.
Pro net-neutrality sites (ie. savetheinternet.com, Google, etc.) are in favor of keeping the system as it currently is. They feel that market power should play no part in how quickly information is transferred, because it would inhibit smaller companies from growing to their full potential.
Anti-net neutrality companies (ie. AT&T, Verizon, etc.) feel that certain programs and information should be given higher priority over others. They do not agree that the government should play such a large part in internet law, and think that giving special treatment to new technologies (such as online gaming) gives way to new innovation.
I personally think that the internet needs to remain the way it is, behaving neutrally towards all data. Corporations and large companies are taking over the rest of the world as it is; the way the internet currently works is so fair, and continues to be one of the few technological "places" one can be without supporting huge companies. The idea of large company having a monopoly over how quickly I, a non-gamer, receive the information I choose, really bothers me. I believe that to remain fair, net neutrality needs to remain in the system of the internet.

Cybersituations.
Before the class in which we learned about Cybersquatting, it had honestly never occurred to me as a serious problem that businesses and companies would have with the internet. I always assumed that, since the internet is an open network for people to add to, it operated on a first-come, first-serve system. In fact, I think this is the way it should operate. Despite whether it is on accident or deliberate, it seems to me that there should not be laws that prevent available hostnames from being used. In fact, it seems almost elitist, seeing that the people who would probably win the coveted hostnames are large, rich companies and large, rich people who have the money and ability to file lawsuit.
Discussion of Cybersquatting also brings up the issue of whether or not one has a "right" to their identity online. How can we argue in favor of this when there are "common" and "uncommon" names, implying that people barely have a right to their own identity in real life?
As far as buying a certain domain with intent to sell, I can equate this to a real estate purchase made while considering that the cost of the property might rise. Although this could be considered "cheap", it is just like any other sales strategy. If the company has a huge problem with thinking of a hostname that is not already available, they should just be able to deal with buying it. Especially the case of Mr. Nissan not wanting to give up his own website just because some auto company makes more money than he does. He scored nissan.com before the other company did, and I say more power to him.

Advance of Technology
I know this entry is coming in really late, but I thought I'd write it anyway.
In just ten years, my usage of technology has increased significantly. Obviously, technology has advanced in that time, but even the uses of the technology that was available did not compare to what is so commonplace today. Now, it seems very natural that one should be able to walk around with thousands of songs at their disposal, to turn on, off, or up -- even to the point where it is considered an inconvenience if such a service is not available! I do, however, remember a time where it was a luxury to carry around more than one CD to play in my discman.
Of all the things that have progressed, internet technology has become possibly the most commonly used. Until I got to high school, websites were not accepted parts of any bibliography. Now, although teachers often request that student include research completed from magazines, books, interviews, etc., I think they are losing the expectation that the students actually will branch out from the web.
The negative influence that I've observed in the internet is that it seems to create an impulsiveness in people that was not previously there. Before there was so much information available, any kind of research had to be premeditated for hours or days. Even finding the right book in the library was work enough to make today's college students wince. Without so many people linked onto social networking sights (Myspace, Facebook, etc.), contact with people not in one's immediate group of close friends was less likely to happen, because with daily updates on Myspace, people do not seem so separated. Although this is not in itself a bad thing, the impulsiveness that is developing in this generation is potentially destructive.
I, however, do realize the positive influence that is so obvious. The internet has changed my habits in a way that I currently recognize as for the better (even though who knows how I will feel in the future). Information is available literally at my fingertips, and just because the research can be conducted as soon as I think of what I want to learn about, I've acquired information that I definitely would not be aware of if I had been forced to take a bus to the library and go through dozens of books that were wrong for what I was looking for. And, the internet now contains sources that are academically acceptable. Even books and magazine articles have been transcribed online. Even though I would be fine with living in the simpler time, it is very exciting to be living through a technological revolution.
