Definition of Web 1.0, 2.0 and 3.0

The Web, born in 1992 at CERN (Conseil Européen pour la Recherche Nucléaire) of Geneva led by Tim Berners-Lee, has gone through several evolutionary phases, which have advanced according to the technologies of the moment and the greater power that the equipment that accesses it has gone winning.

Bliss evolution We can reel it in three basic steps, the first being

Web 1.0, which is the original and primeval, marked by the dissemination of content in one direction

It is defined using the HTML markup language (HyperText Markup Language), derived from XML, and was born under the protection of the scientific community as a standardized way of exchanging knowledge regardless of the computer system used.

Throughout his work at CERN, Tim Berners-Lee found it difficult for him to exchange information with others. scientists from other centers with different computer systems, so he devised a system to facilitate and standardize this practice.

Web 1.0 exceeded all his calculations, and became a standardized system for the publication of any type of information, scientific or not, for

consumption corporate or private.

That original Web did not allow any type of interactivity; the contents were published on the server and, from this, the clients "dragged" them to their computers

While this Web was popularized, technology advanced, and with respect to the Internet, the main novelties that could affect the Web were broadband connections such as ADSL and fiber optic cable, and the managers of contents.

At the same time, the ease of use of the Web made it the front-end of the Internet, that is, the visible face that everyone saw, to the point of identifying the Internet with the Web.

Thanks to this, the facilities that the access providers began to offer and the desire of people to make themselves heard was born the

Web 2.0, which is nothing more than adding a social part to the Web, and a series of technologies that facilitate the publication of content,

such as content managers or CMS that, in turn, make blogs possible, great exponents of what was once the explosion of Web 2.0.

Interactivity is born on the Web, still in a rudimentary way, but which already allows us to interact with others Internet users and those who manage websites more easily than in the past, and without having to send a Message from email.

Speaking of this other service, it is thanks to Web 2.0 that not only webmail services are popularized, but other services that Until then they had needed their own clients, and that they gained Web interfaces, thus facilitating their use by users. end.

The next evolutionary step was Web 3.0, which takes advantage of all the technology to enhance the interactivity, in addition to providing new ways to communicate and also to seek and find the information

It's the web Semantics, in which online applications have taken center stage, from Google Docs to Facebook to online games.

All this made possible, in the first place, by the massive availability of broadband connections and by the evolution of browsers (browsers), which in a race to gain the maximum audience possible, have been incorporating functionalities and allowing you to do things unthinkable a few years ago, such as real-time notifications of updates in websites.

The so-called "cloud" (cloud in English), and which consists of purity in a storage replicated across multiple sites found in different locations, sometimes continents different, and the possibility of launching applications within browsers, has led to the creation of a new paradigm from commercialization of software, selling it not as a product, but as a service.

This, in turn, allows the need to have a operating system concrete installed to run applications.

It is also a time that you have to adapt to small and large screens, those of smartphones and those of the smart TV, and that starts to be something smart thanks to voice assistants like Siri, Google Now or Amazon Alexa.

And, once we have seen these stages, we can ask ourselves, is there Web 4.0? Yes, and it is an intelligent website of which we are already beginning to see "the little leg"

still to horse of the web 3.0. It will be an omnipresent Web, that of the Internet of Things (IoT), which will "understand" what let's say, going beyond what current voice assistants are capable of processing before named.

Thus, we will ask any device (such as our watch or our refrigerator) to “we want a taxi to take us to the airport in half an hour”And our request will be sent to an online server that will request a taxi (which could well be a self-driving vehicle) with the destination of the airport already set.
