Who is tim berners-lee?

Tim Berners-Lee is the Director of the World WIde Web Consortium. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as Web technology spread.

What is 'WWW'?

'www' is short name of the 'Worl Wide Web'. The World Wide Web is a system of interlinked hypertext documents accessed via the internet. With Wed browser, a user views Web pages that may contain text, images, videos, and other multimedia and navigates between them using hyperlinks.

• Tim Berners-Lee said
  “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.” This speech shows motivation of the reserch(the world wide web).
• What is the stated genealogy of the technology?
  –bush’s memex; nelson’s writings on hypertext; berners-lee’s early implementations
• 'WWW' is a collaboratively authored hypertext and standard.
• It like a ISO, IETF, REC...etc.

What is 'URL'?

'URL' is shortname of Uniform Resource Locator, the global address of documents and other resources on the world wide wed.

What is 'HTML'?

HTML(HyperText Markup Language) is the predominant markup language for web pages. It provides a means to describe the structure of text-based information in a document — by denoting certain text as links, headings, paragraphs, lists, and so on — and to supplement that text with interactive forms, embedded images, and other objects.

What is "HTTP'?

• 'HTTP'(hypertext transfer protocol) is an internet protocol designed for transferring information for hypertext documents.
• HTTP development was coordinated by the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF), culminating in the publication of a series of Request for Comments (RFCs), most notably RFC 2616 (June 1999), which defines HTTP/1.1, the version of HTTP in common use.

AFTER CLASS...

A word is so confused. URL, URN, HTTP, HTML ...

This week we studied about 3 topics.
1. what is the media technologies.
2. A short history of computers.
3. Bush's essay "as we may think"

Media technology is a role 'medium' . when digital media technologies connect or separate people, they become media. Example, at the long ago artists use 'egg white' with colors before invent oil colors. These days car is not just moving machine.Most people think 'car' show one's station. if someone have expensive car he is rich. So 'car' is a role medium. media technology is a like 'egg white' and 'car'. Technologies embody social, political, cultural, economic and philosophical ideas and relationships.

George boole is mathematician and philosopher. His main works is invent Boolean algebra. Boolean algebra is the basis of all modern computer arithmetic.
Charles Babbage is mathematician, philosopher, and mechanical engineer. Babbage had designed for the difference engine, an astonishingly complex device for the 19th century. he originated the idea of a programmable computer.

Vannerbar Bush is inventor of "differential analyzer"
Many report, news, studies result are pour out. All information is not independence. scholars get new idea from the other scholars report. But he cannot find long time ago report. they don't have convenience machine. So, Vannevar Bush think imaginary imgormation machine, the "Mamex".
Memex was based on photoelectric microfilm selector. photoelectric microfilm selector is an electronic retrieval technology pioneered by Emanuel Goldberg. Memex is constantly viewed and cited in relation to subsequent develpments in computing, information retrieval, and hypertext.



ps. We always use computer, specially internet. But I don't think 'who is make internet?'.
Bush is person ago 70 years. though he think imaginary information machine, similar hypertext which is we use now. It's very amazing. Bush is genius.
