The document discusses the evolution of the world wide web from Web 1.0 to the proposed Web 4.0. Web 1.0 (1989-2005) was the initial implementation, a "read-only" web of static documents. Web 2.0 (2002-present) enabled a "read-write" web with user-generated content on blogs, wikis and social media. Web 3.0 (proposed) aims to improve data management through structured linked data to enable better discovery and integration across applications. Web 4.0 (proposed future evolution) may feature an "ultra-intelligent" symbiotic web where humans and machines interact through powerful controlled interfaces.

2. World wide web
• World Wide Web (WWW or web) − A hypertext interface to Internet
information resources.
• an information space where documents and other web resources are
identified by Uniform Resource Locators (URLs)
• interlinked by hypertext links
• can be accessed via the Internet
• All the resources and users on the Internet that are using the Hypertext
Transfer Protocol (HTTP).

3. Difference between Internet and Web
• The Internet is a global network of networks while the Web, also
referred to as World Wide Web (www) , is a collection of information
accessed via the Internet.
• the Internet is infrastructure while the Web is served on top of that
infrastructure.

4. Web Page
• Text documents formatted and annotated with Hypertext Mark-up
Language (HTML)
• web pages may contain images, video, audio, and software components
that are rendered in the user's web browser as coherent pages of
multimedia content
• Each page available on the website is called a web page and first page of
any website is called home page for that site.

5. Website
• Multiple web pages with a common theme, a common domain name, or
both, make up a website.
• Website content - largely be provided by the publisher or interactive where
users contribute content or the content depends upon the user or their actions
• informative
• primarily for entertainment
• largely for commercial
• Governmental
• non-governmental organizational purposes

6. Web Server
• Every Website sits on a computer
• Has a unique IP address made up of a series of four numbers between 0
and 256 separated by periods.

7. Web browser
• software installed on your PC
• To access the Web
Netscape Navigator
Microsoft Internet Explorer
Mozilla Firefox

8. FUNCTIONS OF WEB BROWSERS
• The main function is to retrieve information from the World Wide Web and making it
available for users
• Visiting any website can be done using a web browser. When a URL is entered in a
browser, the web server takes us to that website
• To run Java applets and flash content, plugins are available on the web browser
• It makes Internet surfing easy as once we reach a website we can easily check the
hyperlinks and get more and more useful data online
• Browsers user internal cache which gets stored and the user can open the same
webpage time and again without losing extra data
• Multiple webpages can be opened at the same time on a web browser
• Options like back, forward, reload, stop reload, home, etc. are available on these web
browsers, which make using them easy and convenient

9. The Way the Web Works
• A user enters a URL into a browser (for example, Google.com. This
request is passed to a domain name server.
• The domain name server returns an IP address for the server that hosts the
Website (for example, 68.178.157.132).
• The browser requests the page from the Web server using the IP address
specified by the domain name server.
• The Web server returns the page to the IP address specified by the browser
requesting the page. The page may also contain links to other files on the
same server, such as images, which the browser will also request.
• The browser collects all the information and displays to your computer in
the form of Web page.

10. History of WWW
• created in 1989
• By Tim Berners-Lee, working at CERN (The European Organization for Nuclear
Research) in Geneva, Switzerland
• He designed 1st web browser named ‘WorldWideWeb’ in 1990
• He also created:
 Hypertext Mark-up Language (HTML)
 Uniform Resource Identifier (URL)
 Hypertext Transfer Protocol (HTTP)
• 1991 - world wide web opened for business
now “Nexus”

11. Web 1.0
• first implementation of the web
• lasted from 1989 to 2005
• “Web of documents”
• Tim Berners-Lee considers the Web as “read-only” Web
• very passive role
• Technologies include HTML, HTTP and URL

12. • The major characteristics of Web 1.0 are as follow:
• They have read only content.
• Establish an online presence and make their information available to anyone at
any time.
• It includes static web pages and use basic Hypertext Mark-up Language.
• The major limitations of Web 1.0 are as follow:
• The Web 1.0 pages can only be understood by humans (web readers) they do not
have machine compatible content.
• The web master is solely responsible for updating users and managing the
content of website.
• Lack of Dynamic representation i.e., to acquire only static information, no web
console were available to performing dynamic events.

13. Web 2.0
• the second generation of web
• “Web of people”
• Beginning in 2002
• Dale Dougherty in 2004, defined it as a “read-write” web
• web transaction is bi-directional
• implies to flexible web design, creative reuse, updates, collaborative
content creation and modification
• Supports collaboration

14. Characteristics
• Web 2.0 is instead a label coined by Tim O’Reilly and associates to reference the
transition of the World Wide Web to a new phase of use and service
development. The categorization can be used to elaborate on the understanding
of Web 2.0 achieved through varied definitions.
• Technology Centric Definition: Web has become a platform with software above
the level of a single device. Technology that is associated with blogs, wikis,
podcasts, RSS feeds etc.
• Business Centric Definitions: A way of architecting software and businesses. The
business revolution in the computer industry caused by the move to internet as
platform and an attempt to understand the rules for success on that of new
platform.
• User Centric Definitions: The Social Web is often used to characterize sites that
consist of communities. It is all about content management and new ways of
communication and interaction between users. Web applications that facilitate
collective knowledge production, social networking and increases user to user
information exchange.

15. Limitation
• Constant iteration cycle of Change and Updates to services
• Ethical issues concerning build and usage of Web 2.0
• Interconnectivity and knowledge sharing between platforms across
community boundaries are still limited.

16. Web 3.0
• first coined by John Markoff of the New York Times
• “executable Web”.
• to define structure data and link them in order to more effective
discovery, automation, integration, and reuse across various
applications.
• Able to
 improve data management
 support accessibility of mobile internet
 simulate creativity and innovation
 help to organize collaboration in social web.

17. • also known as semantic web
• the concept of website or webpage disappears
• data isn’t owned but instead shared
• services show different views for the same web or the same data
• Main purpose
driving the evolution of the current Web by enabling users to find, share and combine in
formation more easily

18. Web 4.0
• An Ultra-Intelligent Electronic Agent
• Symbiotic web
• Ubiquitous web
• Interaction between humans and machines
• Powerful as human brains
• Progress in the development of telecommunications
• Advancement on nanotechnology in the world
• Controlled interfaces
