WWW are the initials that identify the English expression world Wide Web , the system of hypertext documents that are linked to each other and accessed through Internet . Through a software known as browser , users can view various websites (which contain text, images, videos and other multimedia content) and browse through them through the hyperlinks .
In this way, we could say, using a comparison with the telephone communications sector, that www is the “prefix” that has every portal that is in the mentioned Network that we want to access.
Thanks precisely to the Internet, to the use of the www and, consequently, to the various web pages presented by citizens from all over the world, we have the possibility of accessing endless spaces where we can find information about an aspect we are looking for , where we have the opportunity to entertain ourselves by visualizing 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 that have more influx of users worldwide 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 authentic revolution and innovation of the 20th century and the undisputed axis of the current century. And it has managed to cause an absolute change not only in the technological field but also social.
In this way, expert sociologists have stressed how those have partially modified communication between human beings. And it is not only that many people bet on the Network to be able to have conversations with their friends or family but also a large number of them use the same to meet new friends or relationships, to regain contact with people or even to Establish labor relations.
The WWW, as noted by reviewing the origins of this acronym, was developed in the early 1990s by a man of English origin called Tim Berners-Lee , who had the collaboration of Robert Cailliau , a Belgian who worked with him on Geneva (Switzerland ). Anyway, his background goes back to the 40s. It should be noted that Berners-Lee and Cailliau they have been key to the creation of various standards related to the web universe, as happened with the markup languages that make possible the creation of pages.
The operation of the WWW is considered initiated when a user enters a address (URL ) in your browser or when following a hypertext link included in a page. The browser then drives a series of communications to obtain the data of the requested page and, thus, view it.
The first step is to transform the name of the URL server into a IP adress , using the database known as DNS . The IP address allows you to contact the web server and transfer the data packets.
Then a request is sent HTTP to the server in order to gain access to the resource. First the text is requested HTML and then there is the analysis by the browser, which makes other requests reserved for the graphics and the rest of the files that are part of the page.
