What is WEB 2.0

WEB 2.0

The concept of "Web 2.0" began with a conference brainstorming session between O'Reilly and MediaLive International. Dale Dougherty, web pioneer and 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.

The term "Web 2.0" is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design, and collaboration on the World Wide Web. A Web 2.0 site allows its users to interact 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-based communities, hosted services, web applications, social-networking sites, video-sharing sites, wikis, blogs, mashups and folksonomies.( source: http://en.wikipedia.org)

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 envelopment 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 pages.

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 web-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 (Really Simple Syndication ) 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 tadding 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.
