Third week Sumary(“www: the world-wide web”)
Before we studied this class, professor had mentioned about readings. He said that it is ok that we can’t understand whole readings. It is enough that we can get one idea or thing of readings.
We can number four of key points. It is New media do not replace old media, thy displace them. Meaning(Displace) of this sentence is most important. replace” is that something is there instead of other thing having same functions. However, “displace” is that something is there instead of other thing having little different functions. For example, we can think relationship of between film camera and digital camera. We looked into Burners-lee. He born in UK but he studied for computer science in MIT of USA. He designed network of world(www). People hate to share own research document. However Burners-lee emphasizes the general tendency of world. In a result, CERN, DARPA, INRIA…. are fund www. www is a collaboratively authored hypertext. And it is also a standard(or Language of Network). There are iso, ietf, rfc, w3c. These organization is influenced the www standards. Iso make many international standard.(ex: bolt, nut, machinery, language …). Rfc is manage a request for comments in internet. Communication between CEO and Worker each other is also a request for comments. WWW belongs to the w3c. W3c has no funding of outside. We can join this organization, when we pay $63500/year. It is not commercial. However member of it can learn prior technology of www. We compared http, ftp, smtp, nntp. Http spread hypertext to internet. Ftp is similar web hard but somebody can go in. Smtop is technology of E-mail as Outlook. And www is a vast, heterogeneous network of people and machines. Because so many people use it, there are diffent history, culture … so on. (blog, mini homepage..) And we can see Jevbratt. Jevbratt compared web address from 2001 to 2002. Napier make shredder. He think that when we see a web site, we actually see a harddisk. So shredder shows color related web site.
My opinion
We use www everyday. However I have been not think of www’s origin. Also, I can learn http, ftp, smtp, nntp. And I can learn many organization for standard. I realized importance of standard. WWW’s birth is caused by Burners-lee’s action. World did aware world network but they did not act. I think that thought should not stay thinking, acting is most important.
