Part 1
1.) 1011= 2^3 + 2^1 + 2^0 = 8 + 2+ 1 = 11
2.) 101010= 2^5 + 2^3 + 2^1 = 32+8+2 = 42
3.) 11111= 2^4 + 2^3 + 2^2 + 2^1 + 2^0 = 16 + 8 + 4 + 2 + 1 = 31
4.) 10010 = 2^4 + 2^1 = 18
Part 2
1.) 31 = 2^4 + 2^3 + 2^2 + 2^1 + 2^0 = 11111
2.) 51 = 2^5 + 2^4 + 2^1 + 2^0 = 110011
3.) 7 = 2^2 + 2^1 + 2^0 = 111
4.) 103 = 2^6 + 2^5 + 2^2 + 2^1 +2^0 = 1100111
Part 3
1.) 56 Kbits/sec = 56/8 kbytes/sec = 7 kbytes/sec
7 kbytes/sec = (1/7) sec/kbyte
100 mb= 102400 kb
102400 kby * (1/7) kby/sec = 14,628 sec = 237 min = 3.95 hrs
2.) 5 mbits/sec = (5/8) mbytes/sec = 8/5 sec/mbyte
(8/5) sec/mb * 100 mb = 160 seconds = 2 min 40 sec
3.) 10 mbits/sec = (10/8) mbyte/sec = (8/10) sec/mybte
(8/10) sec/mbyte * 100 mbyte = 80 sec = 1 min 20 sec
4.) 3 mbits/sec = (3/8) mbytes/sec = (8/3) sec/mbyte
8/3 sec/mbyte = 3(60)/8 = 22.5 mb/min
22.5 (60) = 1350 mb/hr
1350mb/hr / 60mb = 22.5 mp3/hr

Net Neutrality
The underlying issue in Net Neutrality is the notion of free speech and economics. Because the internet is neutral now, anyone can start a website that is, in theory, equal to Google. However, most small websites don't reach Google or Ebay proportions. If net neutrality was disabled, bigger websites could afford to purchase "express lanes" to get their information around quicker than these smaller websites. It would be more efficient for high speed video and VOIP, yet it may come at the cost of smaller websites running slower.
Two groups in favor of net neutrality are Save the Internet and the owners of Google. They argue that taking away net neutrality will cause corporations to slow down other websites, favor their own creations, and hinder creativity from new innovators. They push for bills in Congress to regulate who owns and charges for use on the internet, and want to be sure that corporations cannot create a monopoly out of it. Google, in particular, argues that if net neutrality was disabled, a website created by small entrepreneurs would have a difficult time making it into the mainstream. Because they were once a small website which is now the most popular search engine, they fear that charging for a faster connection and better service will drive emerging companies out of business. A website like Google could be offering something great but be left out because of price.
Opponents of net neutrality come largely from HandsOffTheInternet.org, the Republican Party, and corporations like AT&T and Verizon. According to Hands Off, the internet works best with minimal government regulation. They also feel like new technology like VOIP, gaming, and high definition movies would work best if they could charge more for an "express lane" to get these demanding products through to the consumer without limitation. Currently, these products are required to share bandwidth with every other website online, and no special treatment is given between them or any other site.
In my opinion, net neutrality is a good thing. I would rather not have the internet be a monopoly, have tiered payments, or preferred bandwidth for certain things. Though I like watching movies online and talking to my friends abroad with Skype, I think they're both working fine right now and I don't believe that corporations need to control what I do online. Freedom of speech is a fundamental right in the United States, taking it away from the internet would be a tragedy.

Cybersquatting
Cybersquating is a complex issue in today's world; it can be argued that because of net neutrality and freedom of speech that it is legal to use someone's name for profit or make a website similar to another company to get hits. However, I believe that cybersquatting is only respectable when it is used as a form of political protest. For example, whitehouse.org would be, to me, legal because they are protesting the current administration. They are protected under the First Amendment. Cybersquatters who register domain names like stevejobs.com for the sole purpose of cashing in on a trademark or name are breaking the law. Unlike political protesters they are being manipulative and are breaking intellectual property rights. Unfortunately, as in the case for Nissan Motors, if two people share the same name whoever registers first gets the domain. The third form of cybersquating, registering a domain that is a typo of a popular website to host advertisements for money, may be unfair but I don't think it is illegal or can be protected by law. For example, the design website Gamil.com was around years before gmail.com but are often confused. If congress were to pass a law against typo cybersquaters, would they gave to go after gmail.com as well? A law against that would be too confusing to separate the profiteering websites from the legitimate ones.

The Role of the Internet in Daily Life
From the beginning of high school until now the internet has changed greatly. Websites that I reference everyday and that I rely on for research didn't exist, and I couldn't keep in touch with my friends with peer networking sites. During freshman year I relied solely on AIM and email to keep in contact with old friends, but now thanks to Facebook and Myspace, I know pretty much everything about people who I otherwise would have lost touch with. Similar to peer networking sites keeping friends in touch, Craig's List has made local events and want ads so much easier. Thanks to them, the Penny Saver is nearly obsolete! Likewise, Wikipedia wasn't a prominent website yet. It's hard to imagine a time without Wiki, and as much as teachers dislike students using it, it's still a nice starting point for a topic. Lastly, newer video technology has made television available online, even for free on the network and cable station sites. I can watch an episode of Hero's on my laptop if I miss it. Additionally, I can order movies on Netflix and have them sent right to my house (very convenient if you don't have a car!). Because of all these websites, its easier to connect with friends, research, and entertain. However, for every great website that gets developed, there is always a not so great one to counter act it.
Though there have been many wonderful developments on the internet to make my life easier and better, sometimes these can make things a little worse. Thanks to Myspace and Facebook I talk mostly to my distant friends though a computer screen. It would be nice to write a letter but now this form of communication is archaic! Also, Myspace and Facebook are open, so everyone can see anything I post. I've received a lot of unwanted spam websites, "friend" requests from people who I'll never meet, and general junk mail because of networking sites. Easier ways to shop online or on Craig's list have made it so tempting to buy unnecessary things, and not being able to see what you're buying until it's too late has been risky. Having TV readily available at any hour of the day has it's drawbacks as well. It's hard to get homework done knowing that all the episodes of shows I watched as a kid are online (besides I can't see Are you Afraid of the Dark on TV anyway!). Though these are minor inconveniences and temptations for me, the pro's of the internet outweigh the con's.
