Introduction
World Wide Web (WWW) is the system of linked hypertext documents containing text, images, audio, video, animation and much more. The user can view and navigate through these documents with hyperlinks or navigation elements, and references to another document or section have the same document. In a broader sense: "The World Wide Web is the universe of information accessible over the network, an embodiment of human knowledge."
> History of the World Wide Web
WWW was proposed in 1990 by Tim Berners-Lee and Robert Cailliau while working at CERN, the European Council for Nuclear Research. Both came with their individual recommendations for hypertext systems, and later joined them and offered a joint proposal. The term "World Wide Web" was introduced for the first time in this proposal. The story of each invention has many pre-history. Even the World Wide Webalso has many prehistoric progressive development of the hypertext system and Internet protocols, which have made possible the WWW. The gradual development that began in 1945 with the development of Memex, a device for storing large quantities of documents on microfilm, and facilitates the organization of documents. By the year 1968 "hypertext" was introduced, made the connection and organization of documents fairly easy. In 1972, DARPA (Defense Advanced Research Project Agency) project was started,Close all the research centers for the exchange of data, parts which later adopted for military information. In 1979, SGML (Standard Generalized Markup Language) was invented to share documents for major government projects for the separation of content and presentation, and then the same document can be represented in different ways. In 1989 Tim Berners-Lee came with networked hypertext system consisting of laboratory CERN. In 1990, he submitted a joint proposal for the system of hyper text –and the term "World Wide Web, which was first introduced. In 1992 the first mobile browser was released by CERN, and had raised the interest of the sector in the development of the Internet. Today, networking is very popular and has become so fallen into our lives, it is almost impossible to imagine the world without the Internet.
Web development – what and how?
Each technology has some distinctive features and characteristics. Similarly, some Web features, such as data,Services, mess-ups, APIs, the social platform and much more. These features are constantly being developed and progressively in several stages, with quality improvements over the existing one. Web development has been classified and advertised with some fancy marketing terms like "Web 1.0", "web 2.0", "Social Web", "Web 3.0", "pragmatic Semantic Web", "Pragmatic Web," and many others .
Yihong Ding, a graduate student at Brigham Young University, in his article on "Evolution of the Web", explains the development of the Websimilar to the comparison with the human growth hormone. Yihong Ding said: "The relationship between websites and their operators is similar to the relationship between children and their parents. As parents educate their children, maintain and update their Web pages Webmaster. Son of Man have their normal stages of development, as the stage of the infant, pre-school, primary school stage, the adolescent phase, and so on. analogy has its generation Web, as Web 1.0, Web 2.0,and so on. "
Changed along with technological advances web design well beyond the period of time. First draft was just read hypertext system, which allows users to read the information. User was only a spectator of what is represented on the web. Gradually, figures and tables added to the evolution of HTML and web browsers that enables a better design. Development of tools for photo-editing, Web authoring tools and content management tools allowed the designers to create visuallyattractive design layout of the site. In the next phase of development, web design has changed with the change in the usability and direction to its users and not divert the contents of the site. Interacting with the user and social tact must be applied to web design. Now users is not just a spectator. You can drive the net with feedback, information sharing, assessment and personalization. Little by little, we have a sophisticated blend of function, form, content and interaction, as a Read / Write Web The continuation of thisEvolution is the importance of the information displayed on the Web added so that the virtual on-line representatives of the people may be able to read and interpret the information presented. This type of web user agents, that mimic human behavior, read and understand the information with the help of artificial intelligence, such as the "semantic web.
Web 1 0 (Read Only Web)
World Wide Web has developed in stages. The first stage was the basis for "read only" hypertext system as well as Web 1.0As the hype of Web 2.0. Fact in the model originally proposed Web, Tim Berners-Lee, as the web-read / write model with HTTP PUT and DELETE HTTP method. These methods have been almost anything, just because they are used for security reasons.
Some of the features of Web 1.0
1. Constantly involved in Web 1.0 web-master has the responsibility to manage content and update users. Most of the hyperlinks to be assigned manually by the Web master.
2. Web 1.0not support the mass audience. The contents of the site is published by the webmaster and not use it, the collective intelligence of users.
3. Use basic web 1.0 Hyper Text Mark-up language for publishing content on the Internet.
4. Web 1.0 sites do not support the machine readable content. Only people who are web-readers can understand the content.
5. Web 1.0 provides contact information (e-mail, phone, fax or address) for communication. Users have the usethe offline world to communicate with the contact information.
6. In Web 1.0 are web pages designed to react instinctively to the programmed condition. Specific result or a response is generated when the condition is satisfied programmed. Model of Web 1.0 does not, survey distance and can not prepare a response to any request in advance. In order to clearly understand the above characteristics of Web 1.0, Article Yihong Ding on the Evolution of the worldWide Web "is similar to correlate with the world of Web 1.0 world, a newborn.
Baby: I have parents
Web 1.0 site: Webmaster
Baby: Look at me, but I will not explain
Understanding Web 1.0 site: People, not machines
Baby: talk to my parents, if you want to discuss me
Web 1.0 page contact information (e-mail, phone, fax, address, …)
Infant decide: My parents, who are my friends.In fact, I do not
Web 1.0 links page manually specified Web
Babies: Hug me, smile, hit me, I cry (reflex)
Web 1.0 Page: reactive features on Web pages

Web 2 0 (Read Write Web)
"Web 2.0 is the understanding that the network is the platform and the networkRoles platform for the business is different. And the significant role that the user can create added value. And discover how the structure of the database and get things better, so that more people are using it and that is the secret of Web 2.0.
The Web 2.0 is the business revolution in the computer industry have arisen from a change to the Internet as platform, and an attempt to understand the rules for success on the new platform. "[4]
In Web 2.0 the concept of index of consumer prices (the user) and producer (web master) is dissolved. Web 2.ois more on communication and interaction with the user. Web 2.0 is all about participation. "Content is king" is often cited quotation in the first Web 1.0 per day, is now "the user is king" in the Web 2.0 has become. In Web 2.0 users to communicate via blogs, wikis and social networking sites. All that is in the network, to facilitate easy navigation and quick. Web 2.0 is to combine everything into a single page with the help of tagging and AJAX with a better usability in many areas,and a cleaner layout. The API allows programmers the ability to mash up data feeds and databases to cross reference information from different sources on one page. Unlike Web 1.0 and Web 2.0 collective intelligence of millions of users.
Web 2.0 is all about the improved version of the World Wide Web developed with the evolution of the role and business model, where users learned with other users, and not only communication with the editors of CommunicationsContent.
Some of the features of Web 2.0
1. Web 2.0 is the second version of the Web for RIA (Rich Internet Application) for the desktop, such as "drag and drop it on the web page in the browser.
2. SOA (Service Oriented Architecture) is the heart of Web 2.0. Keywords around SOA are RSS feeds, RSS, Web services and mash-up that defines how the Web 2.0 makes application functionality so that integrating other applications and uses them toFeatures that are much richer set of applications.
3. Web 2.0 is the social web. Web 2.0 applications typically interact more with the end user. End users are not only the user of the application, but even if the participants, adding the content, whether to contribute to the wiki, podcast or blog. Given the social nature of the end-user demand is the part of the data range for the application to allow the feedback detection and applicationuse that users will use it.
4. In the Web 2.0 philosophy and strategy is that "The Web is open." The content is available to be moved and modified by any user. Web site content is not from people who have made our site, but to the user that is controlled by the website.
5. Web 2.0 data is the driving force. Users spend more time online and started a period featuring in their liabilities. Web 2.0 requires some of the key technologies for development are usedweb pages. One of the most important is the AJAX technology, developing rich user experience supported.
6. Web 2.0 sites usually also some of the following key technologies.
– RSS (Really Simple Syndication) allows users to syndicate, aggregate, and the creation of disclosure using newsfeeds.
– Union ago mashup that allows content from different sources so that new forms of reuse of information on the public orAPI.
– Wikis and forums to support user-generated content.
– Tagging, users can define and create human-readable key allows web resources.
– AJAX – Asynchronous JavaScript and XML, Web development, which is the technology that allows the interactive exchange of data behind the scenes, without reloading the web page.
In order to clearly understand the characteristics of Web 2.0, you must Yihong Ding's article on "Evolution of the World Wide Web", comparable to correlateWorld of Web 2.0 with the world of a Pre-School Kid.
Pre-School Kid: I have parents
Web 2.0 site: webmaster (owner of the blog)
Pre-School Kid: parents, teach me to know (though often not well organized)
Web 2.0 page Tagging
Pre-School Kid: I understand, but perhaps inaccurate and false
Web 2.0 page Folksonomy
Pre-School Kid: I can provide and distribute news, especially for my parents
Web 2.0 site: BloggingTechnology
Pre-School Kid: Who are my friends are determined mainly by the social activities of my parents and their lessons
Web 2.0: Social Network
Pre-School Kid can be: Several coordinated by us to do something for the individual abilities
Web-2.0-widget webpage, mashup
Pre-School Kid: I can at my suggestion, to communicate with friends
Web 2.0 site: Collective Intelligence
The following table to distinguish the difference betweenWeb 1.0 and Web 2.0

Web 1.0 is about: Hardware costs
Web 2.0 is: free range
Web 3 0 (Semantic Web)
Web link is no longerEncoding of information and resources. Accompanied with the advent of the concept of Semantic Web, the specific information resources or information, so that the machine can understand and read like a human being.
Timer Berner Lee presented
"E '] I have a dream for the Web [in which the computer analysis of all data on the web – content, links and transactions between people and computers. A' Semantic Web ', which should allow this capacity may still happen, but if it happens,Day after day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. What, people intelligent agents "for years has finally spread about."
Semantic Web has drawn from his vision of the Web as a universal medium for exchanging data, information and knowledge. Web 3.0 and Semantic Web is an executable step of development in which dynamic Web applications that offer interactive services and facilitate interaction machine to machine. TimBerner Lee also said
"It will ask again, what is Web 3.0. I think maybe if you included an overlay of scalable vector graphics – everything rippling and folding and looking misty – on Web 2.0 and access to a semantic Web, a space large amounts of data, you must 'll have access to an unbelievable data resource. "Semantic Web is an extension of the World Wide Web in which Web content is expressed in machine-readable language, not only in the nature of language usersAgents can read, process and understand the contents with the help of artificial intelligence that mimics human behavior. In other words: Semantic Web is an extension of content Web cast, which may be independent of intelligent software agents for processing.
Multiple agents can be in the vocabulary of vertical domains program.
Eg
"Travel Agent", which chipset users should hold tickets for the criteria and notify them when it comes to perfectone.
Personal Shopper agent "who always used to find the specific product on eBay and not for you, if one of them, determine compliance with all criteria.
In addition, we have "Real Estate Agent", "Personal Financial Advisor Agent" and many others.
The user needs only his personal agents, with Web services that are exposed to the public and from there take care of many repetitive tasks, creating conversations.
Just Web 3.0 + = Everyone EveryoneEach device + Information
Characteristics of the Semantic Web
1. Unlike websites, database driven, Semantic Web is not the centralized database.
2. Semantic Web is an open system in which the pattern is not fixed, how can a data source.
3. Semantic Web requires the use of meta-description languages, such as Web Ontology Language and the Resource Description Framework (RDF). Note: requires much time and effort.
Web n.0 – Looking Ahead
Let's just another element to the above formula
Everyone = Web 3.0 + + Each device = Everything all the information in the context of technological progress.
Web 3.0 is still under development and will include everything. One can not imagine anything about Web 3.0 technology in progress at present.
Breaking all the features the latest technological developments Raymond Kurzweil, inventor of the OCR (Optical Character Reader) has presented Web 4.0 as a Web operating systemUsers with intelligent agents acting in parallel to the human brain. The following figure shows the evolution of the Web, together with technological progress and the semantics of social relations. Source: Nova Spivack and Radar Networks
Conclusion
The development of the Internet has gone through phases of this article, and introduced many technologies and concepts in various areas, software, communications, hardware, marketing, advertising, content sharing, advertising,Finance and much more.
Somehow, the World Wide Web, how to use to do the things used to change views. I believe that this development is endless and the way to excellence l '.
