Although they are directly related and often supposed synonymous, Internet and the world Wide Web they are different systems.
What this March 12 celebrates is the 30th anniversary world Wide Web, a system of linked pages hypertext (links) and accessible via Internet, That's that it's a huge network of computers distributed around the world.
As the the Web, there are other services that work Internet, like e-mailvoice communications over the Internet and file transfer, among others.
One way to understand the difference is to imagine the Internet as a road network with three essential elements: the routes (physical connections, wiring), the behavior of the drivers (modes of data circulation) and the services provided in paths (e-mails , web pages, vOIP communications).
What does the World Wide Web mean and how does it work?
Before the internet existed, the word "web" in English has been translated as "spider web", For what "World Wide Web" originally meant "Wide World Web". Over the years and popularity that has acquired its other meaning, the web has become synonymous with the Internet and the network.
The World Wide Web is the Internet information retrieval service. As the Encyclopaedia Britannica explains: " gives users access to a wide selection of documents connected to each other hypertext or hypermedia. Hypertext allows the user to select a word in a text and thus access other documents containing additional information about that word.
"The Web works in the basic Internet format client-server. Servers are programs that store and transmit documents on other network computers, if any, while clients are programs that request documents from a server when the user requests it. Browsers allow the user to see the recovered documents ", is detailed in the encyclopedia.
A hypertext document with the text and the corresponding hyperlinks is "written" in HTML language (abbreviations of HyperText Markup Language). Each document is badigned a URL called URL (Uniform Resource Locator).
When, in 1989, Tim Berners-Lee and his colleagues at CERN – an international scientific organization based in Switzerland – began the development of the World Wide Web, they created the HTTP protocol (Hyper Text Transfer Protocol), which standardizes communication between servers and clients.
