Web 2.0

Web 2.0: Web 2.0 is a set of technologies and service that allows people to contribute as much as they consume. The term “Web 2.0” was officially coined in 2004 by Dale Dougherty, a vice-president of O’Reilly Media Inc., during a team discussion on a potential future conference about the Web.
The web 2.0 technologies rely on user generated content and support the provision of interaction among them. Some of the web 2.0 technologies are

Blog: It is a web-based publication consisting primarily of periodic articles normally in reverse chronological order with reflections, comments, and often hyperlinks provided by the writer.

Bookmarking: It allows users to create lists of “bookmarks” or “favourites”, to store these centrally on a remote service (rather than within the client browser) and to share them with other users of the system. Examples include digg, del.icio.us, Netvouz, furl, Connectedy and CiteULike.

Crowdsourcing: The term crowdsourcing was coined by Wired journalist Jeff Howe to conceptualise a process of Web-based out-sourcing for the procurement of media content, small tasks, even solutions to scientific problems from the crowd gathered on the Internet.

Folksonomy: The term folksonomy is generally acknowledged to have been coined by Thomas Vander Wal. It is a collection of tags created by an individual for their own personal use. Folksonomy is the result of personal free tagging of information and objects (anything with a URL) for one’s own retrieval. Examples include discogs.com for music and LibraryThing.

Mashup: A mashup is an element that combines information from multiple systems using Web Services to provide an aggregate service. Personal home pages are an example of a mashup that combines information from disparate sources to a single, personalized web page. Eg. iGoogle Page.

Podcasts: Podcasts are audio recordings, usually in MP3 format, of talks, interviews and lectures, which can be played either on a desktop computer or on a wide range of handheld MP3 devices.

RSS Feed Aggregation Tool: RSS feed aggregation tools gather information from diverse sources across the Web and publish in one place.

RSS: RSS is a family of formats which allow users to find out about updates to the content of RSS-enabled websites, blogs or podcasts without actually having to go and visit the site.

Social Network: A social network or online community is a web based service focuses on building online communities of people who share interests and / or activities by a variety of ways. Example. YouTube (video) Flickr (photographs) and Odeo (podcasts), Myspace, and Facebook.

Tagging: A tag is a keyword that is added to a digital object (e.g. a website, picture or video clip) to describe it, but not as part of a formal classification system.

Wiki: A wiki is a type of editable website that allows users to add, remove, or otherwise edit and change most content very quickly and easily, sometimes without the need for registration by using relatively easy to use wiki syntax.
