WEEK 3: Web 1.0, 2.0, 3.0

WEEK 3: Web 1.0, web 2.0, web 3.0.

A. Web 1.0

It is the first on line work that was formally used in companies in order to show information about them. It was based on HTTP (Hyper Text Transfer Protocol). It was created for business. Nowadays, it is still useful for some organizations (just for information purposes). One of the main characteristics that does not make web 1.0 friendly for the users is that there is no interaction between the owner of the page and the surfers or among the owner, the surfer contributors and the surfer. The user just clicks bottoms and find out information by her/him own.

Web 2.0

According to Wikipedia (2009) “The term Web 2.0 is associated with web applications that facilitate participatory information sharing, interoperability, user-centered design, and collaboration on the World Wide Web.” It is the improvement of web 1.0, specially, because it facilitates communication. It is also known as social network. Web 2.0 is a dynamic web page that has taken into considerations the ideas and feedback of the surfer. That is why users are able to interact with the owner of the web site and also with the surfer contributors. Surfers have two functions now: first, they can use the web page (receive information). Second, they can also add information. They are like a kind of owner of the web side. Common web 2.0 web pages are: facebook, badoo, twitter, among many others.

Web 3.0

If web 2.0 is dynamic, then web 3.0 is even more dynamic because you can be in virtual worlds. It is also known as semantic web. Communication is facilitated by an avatar (a digital character that represents you in the virtual world. Avatars can be people, animals, plants, etc) and you can simulate real life environments. In web 3.0 you can be creative and you can let your imagination fly. One of the most common webs 3.0 that is used nowadays for educational purposes is Second Life.

Web 4.0

The technological development of web 3.0 generates web 4.0. Researchers expect that A.I (artificial intelligence) can be a real thing and not just a science fiction idea. They expect to have on-line agents which think, speak and communicate like human beings do.
