       The concept of "Web 2.0" began with a conference brainstorming session
between O'Reilly and MediaLive International. Dale Dougherty, web pioneer and
                                                  The                 dot
O'Reilly VP, noted that far from having "crashed"(The bursting of the dot-com
bubble in the fall in 2001), the web was more important than ever, with exciting
new applications and sites popping up with surprising regularity.

This article is an attempt to clarify just what is meant by Web 2.0.

The term "Web 2.0" is commonly associated with web applications that facilitate
                         sharing,                      centered design
interactive information sharing interoperability, user-centered design, and
collaboration on the World Wide Web. A Web 2.0 site allows its users to interact
                        ributors                        ,
with each other as contributors to the website's content, in contrast to websites
where users are limited to the passive viewing of information that is provided to
them. Examples of Web 2.0 include web                                   services

                     networking sites,                             blogs

The top buzz words in web 2.0

      Ajax
      Dynamic and static
      Mash-up
      Microblogging
      RSS
      Social bookmarking
      Social networking
      Wiki
      Wikinomics

       Ajax (Asynchronous
       JavaScript and XML) is a
       group of interrelated web development techniques used on the client-side to
       create interactive web applications With Ajax, web applications can retrieve
       data from the server asynchronously in the background without interfering
       with the display and behavior of the existing page. The use of Ajax
       techniques has led to an increase in interactive or dynamic interfaces on web
       AJAX is the art of exchanging data with a server, and update parts of a web
       page - without reloading the whole page.

       Dynamic and static can have several definitions. In computer terminology,
       dynamic usually means capable of action and/or change, while static means
       fixed. Both terms can be applied to a number of different types of things,
such as programming languages (or components of programming
languages), Web pages, and application programs. On a static Web page, the
browser displays an HTML document. On a dynamic Web page, a user can
make requests (often through a form), for data from a server database that
will be assembled according to what's requested.

Mash-ups are web application hybrids that combine two or more webweb-based
information sources to create something new. In this they show the potential
of the Web 2.0 techologies and approaches

Microblogging is the practice of sending brief posts (140 to 200 characters)
to a personal blog on a microblogging Web site, such as Twitter.

RSS with RSS it is
possible to
distribute up-to-date
web content from
one web site to
thousands of other
web sites around
the world.

Wiki is a server
program that allows
users to collaborate
in forming the
content of a Web
site. With a wiki,
any user can edit
the site content,
including other users' contributions, using a regular Web browser. Basically,
a wiki Web site operates on a principle of collaborative trust. The term
comes from the word "wikiwiki," which means "fast" in the Hawaiian
language. The best known example of a wiki Web site is Wikipedia, an
online dictionary building collaboration.

Social networking is the practice of expanding the number of one's business
and/or social contacts by making connections through individuals. Social
networking establishes interconnected Internet communities (sometimes
known as personal networks) that help people make contacts that would be
good for them to know, but that they would be unlikely to have met
otherwise. MySpace and LinkedIn are examples of social networking sites.

 Social bookmarking is tagging a website and saving it for later. Instead
of saving them to your web browser, you are saving them to the web. And,
because your bookmarks are online, you can easily share them with
friends. Social bookmarking is a method for Internet users to share,
organize, search, and manage bookmarks of web resources. Unlike file
sharing, the resources themselves aren't shared, merely bookmarks
that reference them. Folksonomy is also called social tagging,e-mail to a
friend or family member and sent them a link to a website we thought they
might find interesting If so, we have participated in social bookmarking.
