What is the Web 2.0?
It is the term used to designate the stage of the Internet today. The main characteristic of this stage is in the user participation: the web is no longer a one-way communication medium to become multidirectional. Many websites begin to develop with the support of many surfers, as the case of Wikipedia, MySpace, Facebook, Youtube, Blogs, among other places.
How it works?
The current digital language suitable not only for creating interfaces to display information but also include specific modules in order to upload information without having to enter fully into the source code. Although there are sites that do allow users to enter this code (like Linux) that simply represent a barrier for other surfers who are not familiar with building instructions from a programming language.
This is the hallmark of Web 2.0: Include specific tools to put messages (comments, pictures, videos, audio, etc.) on web pages and websites, so that the site is enriched by the participation of society.
What is it for?
The performance of Web 2.0 is much easier to understand by the current Internet users since we continously use web 2.0 tools. Today Internet has transferred to the virtual social interactions that ever happened in local environments. For example, long time ago people shared their photos through albums and invited friends and family for an evening to see them; today the same is done through a website.
