WWW :Privacy

"We are left with the alarming question as to whether privacy should be put before global safety." wrote Abhilash Sonwane of Cyberoam. Among services paid for by publicity, Yahoo! could collect the most data about profitable Web users, about 2,500 bits of in order per month about each typical user of its site and its allied publicity network sites. Yahoo! was followed by MySpace with about half that budding and then by AOL-TimeWarner, Google, Facebook, Microsoft, and eBay. About 27% of websites operate outside .com address.

Standards of WWW

Many formal standards and other technical stipulation define the operation of different aspect of the World Wide Web, the Internet, and computer in sequence exchange. Many of the papers are the work of the World Wide Web Consortium, headed by Berners-Lee, but some are shaped by the Internet Engineering Task Force and other organization.

Usually, when Web standards are discussed, the next publications are seen as opening:

* Recommendations used for markup languages, especially HTML and XHTML, from the W3C. These define the structure and interpretation of hypertext papers.

* Recommendations used for stylesheets, especially CSS, from the W3C.

* Standards for ECMAScript, from Ecma worldwide.

* Recommendations for the text Object Model, from W3C.

Additional publications give definitions of other essential technology for the World Wide Web, including, but not partial to, the next:

* Uniform Resource Identifier, which is a universal system for referencing capital on the Internet, such as hypertext documents and images. URIs, often called URLs, is defined by the IETF's RFC 3986 / STD 66: Uniform Resource Identifier: Generic Syntax, as well as its predecessor and numerous URI scheme-defining RFCs;

* HyperText Transfer Protocol, especially as distinct by RFC 2616: HTTP/1.1 and RFC 2617: HTTP Authentication, which specify how the browser and server validate each other.

World Wide Web working principle

Viewing a Web page on the World Wide Web usually begins either by typing the URL of the page into a Web browser, or by next a hyperlink to that page or resource. The Web browser then initiates a series of communication messages, behind the scenes, in order to fetch and show it.

First, the server-name portion of the URL is resolved into an IP address using the global, dispersed Internet folder known as the domain name system, or DNS. This IP address is essential to contact and send data packet to the Web server.

The browser then requests the resource by distribution an HTTP request to the Web head waiter at that particular address. In the case of a typical Web page, the HTML text of the page is request first and parsed right away by the Web browser, which will then make additional requests for imagery and any other files that form a part of the page. Statistics measuring a website's status are usually based on the number of 'page views' or linked server 'hits', or file requests, which take put.

Having received the essential files from the Web server, the browser then render the page onto the screen as specified by its HTML, CSS, and other Web languages. Any images and other income are included to produce the on-screen Web sheet that the user sees.

Most Web pages will themselves contain hyperlinks to other connected pages and perhaps to downloads, source credentials, definition and other Web resources. Such a collection of useful, linked resources, unified via hypertext links, is what was dubbed a "web" of information. Making it accessible on the Internet shaped what Tim Berners-Lee first called the WorldWideWeb in 1990.

World Wide Web

The World Wide Web is a system of interlinked hypertext documents access via the Internet. With a Web browser, a user views Web pages that may hold text, images, videos, and other multimedia and navigates between them using hyperlinks. The World Wide Web was created in 1989 by British scientist Sir Tim Berners-Lee, working at the European association for Nuclear Research in Geneva, Switzerland, and released in 1992. Since then, Berners-Lee has played an active role in guiding the growth of Web standards , and in recent years has advocate his idea of a Semantic Web.
