"4th week's Summary and Comment"

**Summary**
First, let's look around keypoint about learning until now.

1. When technologies connect or separate people, they become media.
2. Technologies embody social, political, cultural,
economic and philosophical ideas and relationships.
3. When a medium is new, it is often used to simulate old media.
4. New media do not replace old media, they displace them.

explain about media. And this week' keypoint is "People make media and then media make people." It means that some people make media and people is affected by media. For example, massenger has already known by people.

Next, let's see about 'Tim burners-lee'. He is called Internet's father. "A www was developed to be a pool of human knowledge, which would allow collaborators in remote sites to share their ideas and all aspects of a common project." He just made www. He is funded by various deparment.

Also, "what is the stated genealogy of the technology?" The answer is bush's memex nelson's writings on hypertext; berners-lee's early implementations.

Let's back soon again about "what is the www?". A first answer is a collaboratively authored hypertext. Another answer is a standard. The standard is similar to rule. The organization and rule needs for communication because it can not communicate without language.
ISO(International standards organization), IETF(Internet engineering task force), W3C(World-wide web consortium) and RFC(Request for comments) is all accepted with requiring a kinds of comment.

and we saw also Nam June Paik's media art and video art by professor. He's idea is very great! He thought creatively.

and URI(universal resource identifier) is look like web address and it is a sort locator, not location. Also HTML(hypertext markup language) is a sort language form. Html is derived from sgml (standard generalize markup language).

and HTTP(hypertext transfer protocol)- Http is an internet protocol designed for transferring information for hypertext documents.

Then, let's find last answer about "what is the www?" The answer is that "the www is a vast, heterogeneous network of people and machines. The www is more and more increasing, very much variety and connecting between people and people such as blog.

**Comment**
Until now, we have learned about five keypoints. Its is all very important sentences or proper sentences. Expecially this week's keypoint is that people influence media each other. Every week, we have learned about "media". The reason why emphaize media is very important word today. I expect next lecture about another connecting media.
