Web 2.0 is a term that refers to a whole lot of interactive and collaborative aspects of the Internet, and here in particular of the World Wide Web, which appeared in nature from 2004 to 2005.
Web 2.0, also called the “social web“, represents the second generation of intelligent web page development, which facilitates communication, provides secure information and different services, ensures collaboration on the Internet.
So in Web 2.0, it is not about the second version of a software or a web technique. The inventor and promoter of the term Web 2.0 is Tim O’Reilly. For differentiation, the web traditions that existed until the advent of Web 2.0 are called, also symbolic, Web 1.0.
Web 2.0 came about as a result of the transition from Web 1.0, which represents the first implementation of the web and has depended on a multitude of factors. Thus, it appeared in the early 2000s, web 1.5, with which the services offered are diversified, appearing pages containing content management system (CMS), forums, and blogs. Web 1.5 coexists with web 2.0 generation.
Web 2.0 designates new ways to implement and exploit the organizational possibilities of the web. According to them, the content and information on the web is no longer offered to visitors only by the mass media, governments and private companies, but also by private individuals, connected to each other through informal networks based on the Internet, and who actively contribute and participate in making it available. and dissemination of information across the globe. Web 2.0 allows for the creation of blogs, wikis, upload of media content and social networking sites.
Typical examples for this new look are the so-called wikis, weblogs or more simplified blogs, as well as portals and exchanges for images, music, movies/videos and software from the Internet, such as Flickr, YouTube and file sharing websites. Also, so-called “social networks”, such as Facebook or Twitter. Web 2.0 has brought new technologies, such as AJAX, with which you can create complex sites using CMS, XML, RSS, API, etc.
Media across the world have reacted intensely to these new views, even suspecting that they will have direct social and economic effects.
Differences between local and web applications are blurred. Many programs update themselves, linking to their author’s site automatically, sometimes even in secret. The role of the browser is becoming more and more important because with its help today can be implemented extremely complex web applications (see Dynamic HTML). Basically speaking, the browser becomes the most important program of the user.
The roles of “creator” and “consumer” of web pages are beginning to break, because “consumers” are now actively contributing to the creation of new content, as is the case with so-called blogs. Many users move and transform their private sphere from local equipment (their own PC) to the web, making it semi-public or even public.
Mashup is the tendency to simultaneously access and connect with each other more web services from different bidders, but the result appears as “one-piece”, without any interruptions or other disadvantages.
New web-based applications lead to the effect that users, even when not technically well versed, participate directly in the dissemination of information and opinions through the web.
All these recent facets of the web are occasionally referred to as “social software”.
Web 2.B is an extension of web 2.0 dedicated to business, business-to-business (B2B) web. This term applies to a website or an online application based on Web 2.0 principles, but which is focused on the services offered to companies in order to generate business.
