Tanvi Wadekar completed a 100-hour IT training course and project on the World Wide Web (WWW). The document defines WWW as an information system accessed via the internet that allows for the exchange of hypertext documents and other digital resources. It discusses the history of WWW, invented by Tim Berners-Lee in 1989, and its key components like browsers, servers, caches, and protocols. The working of WWW involves connecting to a server via HTTP, requesting an HTML page, and receiving a response before closing the connection. Common elements on WWW are discussed like web pages, bookmarks, directories, sites and URLs. [/SUMMARY]

4. A way of exchanging information
between computers on the
INTERNET.

5. What is WWW
• The World Wide Web (WWW, W3) is an information
system of interlinked hypertext documents and
other digital resources that are accessed via the
internet.
• It has become known simply as the Web. Hypertext
documents are commonly called webpages, which
are primarily text documents formatted with the
Hypertext Markup Language (HTML).
• The network of pages of images, texts and sounds
on the internet which can be viewed using browser
software.

6. History…..
• British computer scientist Tim Berners – Lee is
the inventor of the Web.
• In 1989-1990 he introduce world wide web at
CERN in Switzerland.
• The World Wide Web is often abbreviated as
the Web or WWW or W3.

7. Continued…
• Berners-Lee, In his book Weaving the web he
developed three essential technologies:
– a system of globally unique identifiers for
resources on the Web and elsewhere, the
Universal Document Identifier (UDI), later known
as Uniform Resource Locator (URL) and Uniform
Resource Identifier (URI);
– the publishing language Hyper text Markup
Language (HTML);
– the Hypertext Transfer Protocol(HTTP).

8. HOW WWW WORKS??
• Four basic phases
– Connections
– Request
– Response
– Close

9. Working of WWW.
• First, the user can use the browser to connect
with the server. The browser works by using a
special protocol known as HTTP to request a
specially encoded text from the web server.
• The text written in HTML , which tells the
browser how to response on user’s request.
• Lastly, the user can close the window in the
front of him after his required working.

11. www components:
• Structured components
– Clients/browser: to dominant implementation
– Servers: run on sophisticated hardware
– Caches: many interesting implementation
– Internet: the global infrastructure which facilitates
data transfer

12. Components (cntd..)
• Semantic components
– Hyper Text Transfer Protocol (HTTP)
– Hyper Text Markup Language (HTML)
• Extensible Markup Language (XML)
– Uniform Resource Identifiers (URIs)

13. WEB PAGES
• Web page is a document on the Web. It is a
formatted text document that a Web browser
can display.
BOOKMARKS
• Internet Bookmarks are stored Uniform
Resource Locators (URLs) that can be
retrieved. In internet explorer bookmarks are
saved link and also called as Favorites.

14. WEB DIRECTORY
• A web directory specializes in linking to other
web sites. It is not a search engine and does
not display lists of web pages based on
keywords. Instead, it lists web sites by
category and subcategory.
WEB SITE
• Web site is one or more Web pages that
reside on a single server.

15. Web Site (cntd..)
• It is collection of web pages, images, videos
that is hosted on one or more web servers,
usually accessible via the internet.
• All publically accessible websites are seen
collectively as constituting the “World Wide
Web”.
• The pages of a websites can usually be
accessed from a common root URL called
homepage.

16. Types of Web sites
• Classification according to:
Style
Function
content

17. Classification of Web sites
• Style
I. Static website: A Static Website is one that has web
pages stored on the server in the same form as the user
will view them. It is primarily coded in HTML and it
simply presents pre-defined information to the user.
II. Dynamic Website: A Dynamic Website is one that
does not have web pages stored on the server in the
same form as the user will view them. Instead, the web
page content changes automatically

18. Classification of Web sites
• Functions
I. personal website
II. a commercial website
III. a government website
IV. a non-profit organization website

19. Classification of Web sites
• Contents
1. Personal web site
2. Flash web site
3. E-commerce web sites
4. Affiliate web sites
• Affiliate agencies
• Advertises (ebay)
• Consumers (yahoo)

20. 5. Archive web site
6. Blog web site
7. Community web site
8. Development web site
9. Download web site
10.Employment web site
11.Game web site
12.Search engine web site

21. Uniform Resource Locator(URL)
• URL stands for Uniform Resource Locator. The
URL specifies the Internet address of a file
stored on a host computer connected to the
Internet.
method, scheme
host name domain name top level domain

22. STATISTICS OF WWW

23. Difference between WWW and
Internet
WWW
• The Web is a way of
accessing and sharing
information over the
Internet by using Web
browsers.
INTERNET
• The Internet connects
multiple computers
and forms a network
on which a computer
can communicate with
another computer.

24. Speed issues
• Frustration over congestion issues in the Internet
infrastructure and the high latency that results in
slow browsing. Other solutions to reduce the
congestion can be found at W3C Guidelines for
web response times are:
– 0.1 second (one tenth of a second). Ideal response
time. The user does not sense any interruption.
– 1 second. Highest acceptable response time.
Download times above 1 second interrupt the user
experience.
– 10 seconds. Unacceptable response time. The user
experience is interrupted and the user is likely to leave
the site or system.

25. Conclusion
• WWW is a way of exchanging information. It
is a wider concept.
• Internet and WWW has different meaning.
• Whole world is connected to each other
through World Wide Web
• Establishment chart of WWW shows upward
trend.
