What does Web 2.0 stand for?

Web 2.0, a phrase coined by O'Reilly Media in 2003[1] and popularized by the first Web 2.0 conference in 2004,[2] refers to a perceived second generation of web-based communities and hosted services — such as social-networking sites, wikis and folksonomies — which facilitate collaboration and sharing between users. O'Reilly Media titled a series of conferences around the phrase, and it has since become widely adopted .





Although the term suggests a new version of the World Wide Web, it does not refer to an update to Web technical specifications, but to changes in the ways systems developers have used the web platform. According to Tim O'Reilly, "Web 2.0 is the business revolution in the computer industry caused by the move to the internet as platform, and an attempt to understand the rules for success on that new platform." [3]





Some technology experts, notably Tim Berners-Lee, have questioned whether one can use the term in a meaningful way, since many of the technology components of "Web 2.0" have existed since the beginnings of the internet.[4]

What does Web 2.0 stand for?
The real answer is that Web 2.0 is all about portals site and CMS mixed together to build online communities. In the past Web 1.0 era, which was about 10 years ago till now websites were more like static website (online broshure sites) where each website was hand coded or database driven with static coded sites as datafiles. Today, with better web development languages and business sense technology web designers are creating portal or community building sites to become money making website by finding creative applications to make websites more dynamically useful instead of static. So much cool online applications is now appearing using Web 2.0 creative model. YouTube was born with that model in mind about 3 years it becomes a Billion dollar company no mortar at all. I can wait to see what businesses Web 3.D brings to the future Internet.

Reply:Web 2.0 is a term often applied to a perceived ongoing transition of the World Wide Web from a collection of websites to a full-fledged computing platform serving web applications to end users. Ultimately Web 2.0 services are expected to replace desktop computing applications for many purposes.

Reply:its merely a reference to an adapted set of rules and codes in the web that allows for greater user interaction, media embedding, and appearance adjustments. its generally talking about the web as we know it today instead of the text-based, less multimedia-intensive web of the 90's.
Reply:In alluding to the version-numbers that commonly designate software upgrades, the phrase "Web 2.0" may hint at an improved form of the World Wide Web. Advocates of the concept suggest that technologies such as weblogs, social bookmarking, wikis, podcasts, RSS feeds (and other forms of many-to-many publishing), social software, Web APIs, Web standards and online Web services imply a significant change in web usage. As used by its supporters, the phrase "Web 2.0" can also refer to one or more of the following:





the transition of web sites from isolated information silos to sources of content and functionality, thus becoming computing platforms serving web applications to end-users;


a social phenomenon embracing an approach to generating and distributing Web content itself, characterized by open communication, decentralization of authority, freedom to share and re-use, and "the market as a conversation";


enhanced organization and categorization of content, emphasizing deep linking;


a rise in the economic value of the Web, possibly surpassing the impact of the dot-com boom of the late 1990s.





key principles of Web 2.0 applications:


--------------------------------------...


the web as a platform;


data as the driving force;


network effects created by an architecture of participation;


innovation in assembly of systems and sites composed by pulling together features from distributed, independent developers (a kind of "open source" development);


lightweight business models enabled by content and service syndication;


the end of the software adoption cycle ("the perpetual beta");


software above the level of a single device, leveraging the power of The Long Tail;


ease of picking-up by early adopters.





A Web 2.0 website may typically feature a number of the following techniques:


-------------------------------------


Rich Internet application techniques, optionally Ajax-based


CSS


Semantically valid XHTML markup and the use of Microformats


Syndication and aggregation of data in RSS/Atom


Clean and meaningful URLs


Extensive use of folksonomies (in the form of tags or tagclouds, for example)


Use of wiki software either completely or partially (where partial use may grow to become the complete platform for the site)


Use of Open source software either completely or partially, such as the LAMP solution stack


XACML over SOAP for access control between organisations and domains


Weblog publishing


Mashups


REST or XML Webservice APIs





Innovations associated with "Web 2.0"


----------------------





1.Web-based applications and desktops


2.Rich Internet applications


3.Server-side software


4.Client-side software


5.XML and RSS


6. Specialized protocols


Specialized protocols such as FOAF and XFN (both for social networking) extend the functionality of sites or permit end-users to interact without centralized web-sites.


7.Web protocols


Web communication protocols support the Web 2.0 infrastructure. Major protocols include REST and SOAP.





REST (Representational State Transfer) indicates a way to access and manipulate data on a server using the HTTP verbs GET, POST, PUT, and DELETE


SOAP involves POSTing XML messages and requests to a server that may contain quite complex, but pre-defined, instructions for the server to follow








hope this will help!!

Reply:It is a newer version of the World Wide Web that revolutionized the way we surf the web. This ranges from the services we get from the convenience of its usage itself.
