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
