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.
