WWW

WWW are the initials that identify the English expression World Wide Web , the system of hypertext documents that are linked to each other and which are accessed through the Internet . Through software known as a browser , users can view various websites (which contain text, images, videos, and other multimedia content) and navigate through them using hyperlinks .

In this way, we could say, using a comparison with the telephone communications sector, that www is the "prefix" of every portal that is in the aforementioned Network that we want to access.

Thanks precisely to the Internet, to the use of the www and, consequently, to the various web pages that citizens from all over the world present, we have the possibility of accessing endless spaces where we can find information on an aspect that we are looking for , where we have the opportunity to entertain ourselves by viewing interesting images or even where we can communicate with people from any corner of the geography of our planet.

In this sense, and based on the examples presented, we can underline that some of the websites with the highest influx of users around the world are the Google search engine , the YouTube video portal or social networks such as Facebook .

It is worth noting that for all this, the Internet and the www world has become the true revolution and innovation of the 20th century and the undisputed axis of the current century. And it is that it has managed to bring about an absolute change not only in the technological field but also socially.

In this way, expert sociologists have highlighted how they have partly modified communication between human beings. And it is that not only is it that many people bet on the Internet to be able to have conversations with their friends or family, but also that a large number of them use the same thing to meet new friends or relationships, to regain contact with people or even to establish labor relations.

The WWW, as noted when reviewing the origins of this acronym, was developed in the early 1990s by a man of English origin named Tim Berners-Lee , who had the collaboration of Robert Cailliau , a Belgian who worked with him in Geneva ( Switzerland ). Anyway, its antecedents go back to the 1940s. It should be noted that Berners-Lee and Cailliau have been key to the creation of various standards related to the web universe, as happened with the markup languages ​​that make the creation of pages possible.

The operation of the WWW is started when a user enters an address ( URL ) in his browser or when he follows a hypertext link included in a page. The browser then triggers a series of communications to obtain the data of the requested page and, in this way, display it.

The first step is to transform the server name of the URL into an IP address , using the database known as DNS . The IP address allows you to contact the web server and transfer the data packets.

An HTTP request is then sent to the server in order to gain access to the resource. First the HTML text is requested and then the analysis by the browser takes place, which makes other requests reserved for the graphics and the rest of the files that are part of the page.
