Abstract

Web 2.0 is the evolution of the Web towards greater simplicity (requiring no technical knowledge or computer for users) and interactivity (allowing everyone, individually or collectively, to contribute, share and collaborate in various forms). The term “Web 2.0" means all technical, features and uses of the World Wide Web that follow the original form of the web, especially interfaces that allow users with little technical knowledge to adopt new functionality of the web. Thus, users contribute to the exchange of information and can interact (share, exchange, etc.) simply, with both the content and structure of the pages, but also between them, creating this way the social web. The user is using the tools at its disposal, as an active person on the canvas. The term “2.0" is now used as a generic term to apply the concept of Web 2.0 to other application domains.
