정보기술개론 3월 5주 (3/28)

In Last class, We learnd about "The World Wide Web".

The key point of this class was "People make media and then media make people."

Media make people means media make how people think about.

For instance, The messenger, People was born after messenger was born.

That is messenger influence thinking method of peoples.

Also name is same, too. Before baby is born, his or her family often make his or her name.

This is another paraphrase from Marshall McLuhan’s book Understanding Media which

was, in turn, a paraphrase of something Winston Churchill said about architecture.

Then, we talked about tim berners-lee that he was senior research scientist,

founder chair, lcs (laboratory for computer science), mit; and director of the

world-wide web consortium. Also he was consultant at cern European unclear research

center. He thought about communicating method, and he tried networking, WWW.


what is the www?




WWW is a collaboratively authored hypertext which it is a standard.

The 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.

Problem of this research address was that the work was to provide a graphical

interface to a set of distributed files used in physics project management at CERN.

Language is standard. Like this, WWW's all process is standard.

Also WWW connects between people and people.

www is standard for networking. ISO (international standards organization) is

a network of national standards institutes from 145 countries working

in partnership with international organizations, governments, industry,

business and consumer representatives. It acts as a bridge between public

and private sector. It has created over 12,000 standards. If ISO was not exist,

we could not share information. Because ISO is standards.RFC (request for comments)

is kind of technical system. RFC can comment and reply. RFC means that listens opinion,

and corrects problem. It is one to one system. There are not head, order.

w3c (world-wide web consortium) develops web standards and guidelines.

There are current members around 400. It is opened. It is not company.

We also talked about URI (universal resource identifier) is persistent location.

Urn is in a specific name, a specificre source. For example, url(ssu name), urn(persistent

location: declare). url is adress wide ranged.Html (hypertext markup language)

is derived from sgml (standard generalize markup language). Http (hypertext

transfer protocol) is an internet protocol designed for transferring information

for hypertext documents. Network protocol is a set of rules used when computers

send information across the network. Http compares this to ftp (file transfer protocol),

smtp (simple mail transfer protocol), nntp (network news transfer protocol), etc.

Media and peoples are in interaction. That's so interesting.And, WWW is very useful.

But I didn't know what is WWW. So this class helped me. WWW is complex, and exciting.

There are so many function
