The notion of the web is used to name a computer network and, especially, the Internet. The idea of web 3.0 refers to a kind of extension or particular format of the traditional network.
It is important to bear in mind that the concept does not have a specific definition, but is often the subject of debate among specialists. In principle, to understand what web 3.0 is, you have to know what the two previous “versions” of the web refer to.
The web 1.0 is Internet in its classical sense: decentralized network of computers (PCs), linked through a specific protocol. Entering a newspaper's website would be an example of the typical operation of web 1.0: the information is found on a computer and users, through another computer, access a copy of it to read it locally.
The web 2.0 is linked to the services that allow you to share data and interact with ease. Social media and collaboration platforms are the foundation of this evolution of the Internet.
The idea of web 3.0, in this context, is related to what is known as the semantic web. Users and computers, in this framework, can interact with the network through a natural language, interpreted by the software. In this way, accessing the information is easier. In other words, all data hosted on web 3.0 should be "understood" by machines, which could process it quickly.
The web 3.0, in short, is related to artificial intelligence. The websites would even have the ability to connect with each other according to the interests of the user.
In the first place, the reason that there is no formal definition or a single definition of web 3.0 is because many people are working on their own vision of the future of the Internet, so each one expects different changes and improvements in the web browsing experience.
Returning to the evolution of the Internet, we can say that in the beginning each site had its own information and did not share it with others: text and images, for example, which were part of the code itself and, therefore, were indivisible from the page in the one that was shown.
One of the barriers that Web 3.0 tries to break down is the need for human operators to evaluate and manage content on the Internet. This is not new, since several companies, among which Google stands out for the popularity of its products, have spent years researching and developing artificial intelligence technologies to make browsing increasingly fluid and enriching.
Today we can access the Internet from a myriad of different devices, and this variety brings many new challenges for developers, both in terms of website aesthetics and technical issues related to applications and data transfer. Web 3.0 aims for all of us to be able to enjoy information and Internet tools regardless of the device through which we connect, since it seeks flexibility and versatility that overcome the barriers of format and structure.
