Meaning: World Wide Web (WWW), Byname the Web, the Leading Meaning: World Wide Web (WWW), byname the Web, the leading information retrieval service of the Internet (the worldwide computer network). The Web gives users access to a vast array of documents that are connected to each other by means of hypertext or hypermedia links— i.e., hyperlinks, electronic connections that link related pieces of information in order to allow a user easy access to them. Hypertext allows the user to select a word or phrase from text and thereby access other documents that contain additional information pertaining to that word or phrase. Hypermedia documents feature links to images, sounds, animations, and movies. The Web operates within the Internet’s basic client-server format; servers are computer programs that store and transmit documents to other computers on the network when asked to, while clients are programs that request documents from a server as the user asks for them. Browser software allows users to view the retrieved documents. The World Wide Web is a network of online content that is formatted in HTML and accessed via HTTP. The term refers to all the interlinked HTML pages that can be accessed over the internet. It is technically all the web pages, videos, pictures and other online content that can be accessed via a web browser. The world wide web, or WWW, was first created as a method to navigate the now extensive system of connected computers. It was designed by Tim Berners-Lee through a rudimentary hypertext program called Enquire. The WWW is what most people think of as the internet. But as a matter of fact, the internet is the underlying network connection that allows us to send an email and access the world wide web. Web earlier was a collection of text-based sites hosted by organizations that were technically able enough to set up a web server and learn HTML. Since then, it has only continued to evolve the original design, and now includes many other useful elements like social media and user- generated content that requires minimal technical skills to use. Evolution: The WWW was introduced and originated by a contractor named Tim Berners-Lee who worked with the European Organization for Nuclear Research developed Enquire-a rudimentary hypertext program. This program was designed in a way in order to make information readily available to users. It also focused on allowing a user to explore relationships between different pages by clicking to get to a different section of a website. In 1990, Tim Berners-Lee and other scientists at the international organization called CERN (European Center for Nuclear Research) in Geneva, Switzerland, developed a computer protocol called the HyperText Transfer Protocol (HTTP) that became the standard communications language between Internet clients and servers. Exchanges of information on the Internet take place between a server (a computer program that both stores information and transmits it from one computer to another) and a client (also a computer program but one that requests those transmittals of documents from the server). The client is not a person; the person giving instructions to the client is called a user. The first Web server in the United States was the Stanford Linear Accelerator Center (SLAC) in Palo Alto, California. To be able to look at retrieved documents, the user's computer is equipped with browser software. The programmers at CERN also developed a text-based Web browser that was made public in 1992; they also proposed the name World Wide Web for their system. Documents that comply with the HTTP protocol are called hypertext documents and are written in HyperText Markup Language (HTML) which includes both text and links. Links are formally called hypermedia links or hyperlinks that connect related pieces of information through electronic connections. Through links, users can access arrays of documents identified by these shared links. Documents consisting of text are identified through hypertext; and other kinds of information like photos and other images, sounds, and video are identified as hypermedia. Users find and access hypertext or hypermedia through addresses called Uniform Resource Locators or URLs. URLs often contain the letters "http," "www," and "html" showing that, within the HTTP rules, they want to access the World Wide Web by speaking in HTML. Features: World-Wide Web (WWW) is a hypertext-based information system. Any word in a hypertext document can be specified as a pointer to a different hypertext document where more information pertaining to that word can be found. The features of www are as follows: HyperText Information System. Cross-Platform. Distributed. Approximately 70 million active sites as of December 2007. Open Standards and Open Source. TCP/IP, HTTP, HTML, CSS. Web Browser: provides a single interface to many services. Dynamic, Interactive, Evolving. The amount of information available on the Internet has become so large that it is difficult to search for specific information. The World Wide Web (WWW) makes retrieval easy and quick. The WWW is a search tool that helps you find and retrieve information from a Web site using links to other sites and documents. The WWW was built on the technology called Hypertext. This technology increases accessibility to linked documents on the Internet and helps user to navigate between documents very easily. Hypertext is identified by underlined text and a different color usually. Some places will refer to this types of technique as Jump-Off Points. Hypertext can make links within the same document or to other documents. Each time you access a new document by choosing a link, there is a connection made with the web server that the document is on. Once the appropriate document is retrieved the connection is broken. There is no point in maintaining the link while you are viewing it. This is one reason why the WWW is so efficient. WWW lets you search, traverse, and use many types of information at numerous sites and in multiple forms. This interface is called a browser. Some people refer to a browser as a 'web browser' often these terms are used interchangeably. The WWW is intended to help people share information resources, and services with the widest possible community of users. Thus a user can access the WWW on Apple, UNIX, Macintosh, DOS, Windows, and other operating systems. Just like the Internet, the WWW has a protocol, which is known as HyperText Transfer Protocol (HTTP). HTTP acts as an interface between a Web Client Software, such Netscape Navigator. A major advantage of the WWW is that it also supports TCP/IP services, such as Gopher, FTP, and Archie in addition to HTTP..

Created in 1990 by Tim Berners- Lee, the web quickly became the most used hypertext system in the world, and most browsers default to indicating hyperlinks with an underline. To answer the question of why the underline was chosen over competing demarcation techniques, the thesis applies the methods of history of technology and sociology of technology. Before the invention of the web, the underline–also known as the vinculum–was used in many contexts in writing systems; collecting entities together to form a whole and ascribing additional meaning to the content.

  • E-Learning 3.0 = E-Learning 2.0 + Web 3.0?
    IADIS International Conference on Cognition and Exploratory Learning in Digital Age (CELDA 2012) E-LEARNING 3.0 = E-LEARNING 2.0 + WEB 3.0? Fehmida Hussain Middlesex University, Dubai ABSTRACT Web 3.0, termed as the semantic web or the web of data is the transformed version of Web 2.0 with technologies and functionalities such as intelligent collaborative filtering, cloud computing, big data, linked data, openness, interoperability and smart mobility. If Web 2.0 is about social networking and mass collaboration between the creator and user, then the Web 3.0 is referring to intelligent applications using natural language processing, machine-based learning and reasoning. From the perspective of advancements in e-Learning, the Web 2.0 technologies have transformed the classroom and converted a passive learner into an active participant in the learning process. This paper posits that the way both previous generations of e-Learning (1.0 and 2.0) have emerged with the prevalent technologies in their kin Web versions (1.0 and 2.0, respectively), it can be argued that e-Learning 3.0 will provide all earlier generations’ capabilities enhanced with the Web 3.0 technologies. Furthermore, in this paper, reviewing all the theories of learning and examining closely the theory of connectivism (considered to be the theory of learning for the digital age), it is argued that since most of the technologies that are to be a part of e-Learning 3.0 are addressed by these principles, a call for a new learning theory for e-Learning 3.0 is not justified.

    World Wide Web - Wikipedia, the free encyclopedia http://en.wikipedia.org/w/index.php?title=World_Wide_Web&printabl... World Wide Web From Wikipedia, the free encyclopedia The World Wide Web , abbreviated as WWW and commonly known as The Web , is a system of interlinked hypertext documents contained on the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks. Using concepts from earlier hypertext systems, British engineer and computer scientist Sir Tim Berners Lee, now the Director of the World Wide Web Consortium, wrote a proposal in March 1989 for what would eventually become the World Wide Web. [1] He was later joined by Belgian computer scientist Robert Cailliau while both were working at CERN in Geneva, Switzerland. In 1990, they proposed using "HyperText [...] to link and access information of various kinds as a web of nodes in which the user can browse at will",[2] and released that web in December. [3] "The World-Wide Web (W3) 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." [4] If two projects are independently created, rather than have a central figure make the changes, the two bodies of information could form into one cohesive piece of work.

It defines the qualities of the hypertext narrative and looks specifically at how hyperfiction has utilized these qualities. It outlines the aspects of hypertext relevant to shaping an online narrative and then considers how those aspects of hypertext could be applied to one of the forms of narrative, the online news story, that up to this point has not effectively utilized screen-based text. The online news story is an example of words on a screen functioning in much the same way they have for hundreds of years on the newspaper page. This thesis focuses specifically on the application of hypertext theory to online newspaper because of the precarious place in which that media finds itself as it works to adapt to the age of the Internet.

  • Vision and Reality of Hypertext and Graphical User Interfaces
    Universität Hamburg Fachbereich Informatik Vogt-Kölln-Str. 30 D-22527 Hamburg Germany Bericht 237 Vision and Reality of Hypertext and Graphical User Interfaces FBI-HH-B-237/02 Matthias Müller-Prove [email protected] In die Reihe der Berichte des Fachbereichs Informatik aufgenommen durch Prof. Dr. Horst Oberquelle Prof. Dr. Christopher Habel Februar 2002 Abstract The World Wide Web took off ten years ago. Its tremendous success makes it easy to forget the more than forty years of hypertext development that preceded the Web. Similarly, modern graphical user interfaces have drawn attention away from the many compelling ideas behind earlier user interface designs. In the present thesis, numerous early hypertext and graphical user interface systems are presented and contrasted with today's Web and desktop interfaces. The designers of early hypertext and graphical user interface systems shared a common objective: the development of a personal dynamic medium for creative thought. Not very much is left from this original vision. Retrospect reveals promising insights that might help to reconcile the desktop environment with the Web in order to design a consistent and powerful way to interact with the computer. Zusammenfassung Das World Wide Web hat vor nunmehr über zehn Jahren seinen unvergleichlichen Siegeszug begonnen. Dabei wird oft übersehen, daß die Idee des Hypertexts eine bereits über vierzigjährige Geschichte hinter sich hat. Die Arbeit zeigt diese Entwicklung anhand der verschiedenen Hypertextsysteme auf und kontrastiert sie mit dem Web. Die Betrachtung der Grafischen Benutzungsoberflächen zeigt ganz ähnlich, daß auch hier viele gute Ideen auf dem Wege zu den heute dominierenden Fenstersystemen verloren gegangen sind.

  • The World Wide Web Consortium by Alla Zollers
    The World Wide Web Consortium by Alla Zollers IS297 Information Institutions March 15, 2007 Dr. Maack Introduction Imagine a world where you have to use a special browser in order to access online information outside of the US, or a world where a person that is utilizing a PC would not be able to view the same web pages as a person using a Mac. We could speculate that in such a world, the diversity, popularity, and spectacular growth of the Internet would not have been possible. Only through worldwide standardization of the ways in which web pages are coded, displayed, and accessed has the World Wide Web been able to flourish into the international phenomenon that it is today, and also become a vital part of our lives. When Tim Berners-Lee was inventing the World Wide Web he was working from the fundamental principle that “once someone somewhere made available a document, database, graphic, sound, video, or screen at some stage in an interactive dialogue, it should be accessible … by anyone with any type of computer, in any country,” (Berners- Lee, p. 37). It seems that Tim Berners-Lee understood from the beginning that in order for the World Wide Web to be successful, everyone in the world should be able to contribute to it as well as to access it. So it logically follows that Tim Berners-Lee was also responsible for creating the World Wide Web Consortium (W3C). W3C is an “international consortium where Member organizations, a full-time staff, and the public work together to develop Web standards,” and whose mission is, “To lead the World Wide Web to its full potential by developing protocols and guidelines that ensure long- term growth for the Web,” (W3C Website).
