We use the Web on a daily basis, it has become
part of our lives, specially for new generation of students. However, some of
us do not have really clear what the Web is. In
this post I will expose a little bit about the terminology and evolution of the
Web. Let’s start from the basic terminology:
- What does “The Web” mean?
Web is the acronym for World Wide Web. Basically,
is a collection of interconnected documents or content which works on the basis
of the client and service relation: the web client requests the use to the web service, the main purpose is facilitate the exchange of information between
people and computers.
The World Wide Web was created by Tim
Berners-Lee. He presented his first proposal on 1989, but it wasn’t until almost
20 years after that the web was establish on the Internet. When he came up with
the idea of exchange information though computers, he was working as a software
engineer at CERN, The European Organization for Nuclear Research. He observed
many scientists participating on CERN experiments and then returned to their
laboratories to work by themselves. After the individual research, they had
problems exchanging results. Berners-Lee could observe their necessity to connect
and exchange content via their computers. Seen this opportunity, he presented
his firth proposal, but it was rejected. (World Wide Web Foundation, "History
of the Web")
In 1990, he had created the first web page
editor, browser and server. From those first steps until
now, the Web has evolves rapidly, changing our communication and lifestyle.
- Web 1.0
At the beginning, the main purpose
of the Web was to serve as a cyberspace that allows people to share
information. Thus, Web 1.0 works primary as a source of information, were the
users could only read it. The Web was static and mono-directional, this means
that the service provides information to the user, but he couldn’t modify it or
contribute, therefore the websites were not interactive. Its main clients were
business and companies that want to publish their catalogs and services, so people
could read about it.
- Web 2.0
This web allows users to read
and write information, it was bio-directional because the web service presents
information to the user and he could also add information to it, thereby allows
interaction. For example, the web 2.0 technologies
and services include blogs, wikis and tags.
Facebook was born as a platform to
share, upload and comment information; in the beginning, its users were
primarily university students who exchange content about their social
live.
- Web 3.0
Also know as the “semantic
web” because its main purpose is to be readable to machines and humans, using information
in the way computers can read it. It’s a web of documents,
compared to a global database, were the information (or data) is decoded first
by computers, and then by people. One of
its attribute is the “mobility” characteristic, thus you can find the web in
everything at any time: in computers, mobile devices (such as smart phones) and
even in appliances. Another feature is that it can anticipate the user
preferences.

According to "History of the Web" (World
Wide Web Foundation), since 1989 “the Web has
changed the world. It has arguably become the most powerful
communication medium the world has ever known. (…) the Web has changed the way
we teach and learn, buy and sell, inform and are informed, agree and disagree,
share and collaborate, meet and love, and tackle problems ranging from putting
food on our tables to curing cancer.”
As we saw, the Web evolves continuously changing how we communicate and our interaction with each other. From Web 1.0 to Web 3.0, education has
also changed according to the technology evolution. Nowadays, teachers and
students can share information transcending time and borders, taking advantage
of the new technology.
