Day 25: spam outline

My group consists of Dawn, Julia, and Me. We are Team 6- Spam. Our presentation will look something like this:
-Julia- what is spam? who clicks on spam? what money is made from spam? famous spammers?
-Me- is spam legal? recent cases in the news. difference between spam and junk snail mail.
-Dawn- Spam in relation to telemarketing. How do you find out who is sending the spam? (using the url). How do you get rid of spam? ways to protect against it.

We will each expand on our areas and add anything from new areas we find. My best sources so far are:

These sources cover both the legality of spam, and recent spam court cases. I will sort through the information, grab the most important pieces, and incorporate them into the talk.

Spam

My group's topic for mondays presentations is Spam. There are many different types of spam- through emails, instant messaging, and online games. It is basically sending unsolicited bulk messages that users most likely do not want to see. Most of the people making spam do not have many costs other than the list they send spam to, and it is hard to hold these mailers accountable. Spam is also known as "junk mail" that shows up in your inbox. Spammers get addresses from chat rooms, email addresses listed publicly on the web, and directories of large e-mail hosting companies. Spam filtering software can help you avoid Spam, which also helps reduce the bandwidth that spam eats up. Spam costs a lot less than physical junk mail- instead of using paper and postage, a spammer can send an email to thousands of people without costing much at all. Overall, spam is very annoying for those who receive it, but makes money easily for those sending it.

How does email work?

Email is one way-a very popular way, to use the internet. It is a piece of text sent from a user to a recipient. This peice of text that you type is usually broken down into packets that are then transported through the mail server. One email is usually sent in steps, or "hops". There are a few thigns you must need to send the email. first, you need to be connected to a mail server that is able to transfer your message. Also, the address you send to must have a valid name and domain, which the server will locate. The client that receives the email puts the packets back together into a form a person can understand. Email is actually very similar to snail mail. You must have a way to send your mail (post office), and a destination (recipient address). However, email is much faster and is broken down during travel, but the two concepts are actually very similar.

Day 18

-Network Neutrality is basically a principle that says all internet access should be equal- without anything being blocked or limited by the internet provider.
-Limited discrimination without teiring= United States lawmakers have introduced bills that would allow quality of service discrimination as long as no special fee is charged for higher-quality service.
-limited discrimination and teiring= This approach allows higher fees for QoS as long as there is no exclusivity in service contracts. According to Tim Berners-Lee: "If I pay to connect to the Net with a given quality of service, and you pay to connect to the net with the same or higher quality of service, then you and I can communicate across the net, with that quality of service.""[We] each pay to connect to the Net, but no one can pay for exclusive access to me."
-Many major internet companies are advocates of neutrality, including: Google, Yahoo, Vonage, Amazon
-some engineers oppose neurtrality. they have a website called Hands Off the Internet, which is funded by AT&T
-http://news.cnet.com/8301-30686_3-10357806-266.html
-AT&T opposes network neutrality- government should stay out of regulation. companies must limit certain elements
-AT&T is one of the largest holding companies in the world by revenue. serves 78.2 million customers. more than 16.9 internet subscribers. had a net income of $2.4 billion in 4th quarter of 2008. $3.2 billion in 1st quarter of 2009. serves individuals and small businesses
-smiliar feelings about wireless neutrality as Verizon
-AT&T has called google a hypocrit and says they violate their own terms about net neutrality http://news.cnet.com/8301-30686_3-10362148-266.html

Day 17

My current IP address is 152.33.48.254.
I looked up the company my dad works for on networksolutions.com. His website is www.bottles.com, and when I searched this is could see his company Custom Bottle, Inc. They registered the domain in 1996 and it expires in 2010. The link to this information is http://www.networksolutions.com/whois-search/bottles.com. One of the employees is also listed as the contact person.

Day 16

The word I was sent is Willywaw. According to yourdictionary.com, willywaw is a noun meaning a sudden, violent, cold wind blowing down from mountain passes toward the coast in far northern or southern latitudes, as on the Alaskan coast and Aleutians, and in the Strait of Magellan. It can also mean a state of extreme confusion, turmoil, or agitation. The word I was trying to send is cudweeds, which are any of several composite plants with silky or woolly foliage.

It took me a very long time to send my message. It seemed that someone always spoke right as I was about to, or I would get into a collision when trying to send my message. I was one of the last people to successfully send my entire message. I thought it was much easier to receive a message than send one. When receiving, you need to pay attention but the person sending me a message was very good at talking slowly and getting the message through clearly. There were so many collisions that sending the message was very hard. I also had to be careful when saying my message to make sure I spoke slowly enough for the person receiving it.

Some problems were that everyone spoke at the same time. You also had people who would get into a collision but would keep trying rapidly, not elaving anyone else time to send their message It seemed there were a few people who were very prominent in trying to get their message through loudly and aggressively. Another problem was that people spoke too quickly for their receiver. I thought the best way to solve this was to go in a circle around the room. That way, everyone would get a turn to say and recieve their message. No matter what, there may be issues or collisions, but this is probably the most efficient way to get messages across.

Networking problems

In a bus topology, addressing and communication conflicts are complicated but must be solved. With the problem of addressing, one solution could be to name each computer distinctly with a number. This would help with sending a message to a certain computer. It would be important not to repeat numbers, so that your message could be delivered to the correct destination.

Communication gets complicated because the wires in the network must handle many different tasks at once. To help prioritize what messages gets transfered first, you could assign priority to each computer. Each computer would have a number as their name, which also could correspond to how important they are or how fast their messages get sent. For example, in a classroom, the teacher's computer would be named number one becasue it is most important and probably needs to do the most work. Adding more wires so that more information can flow would also be helpful.
