INTRODUCTION
Internet is one of the words most recently named by those
approaching technology or computer science. Internet brings
a large set of denotations and connotations, according touser groups, and services changing and evolving. With over
200 million users worldwide, the Internet has become the
most widespread means of communication in the history of
mankind.
Is a source of information and knowledge sharing
worldwide. It is also the communication channel that allows
for cooperation and collaboration between many
communities and interest groups on specific topics,
distributed throughout the world.
You can find all sorts of software for a wide variety of
computers and operating systems, please consult the
catalogs of libraries in the world, access databases with the
most diverse and transfer copies of the documents found,you can view Copying Images and photographs of any kind or
reproductions of paintings, can be things like real-time chat
two people separated by thousands of miles away, can
communicate through Internet by typing on the computer.
How will interconnection network "Internet is changing
traditional patterns of doing things?, Is one of the questions
this research seeks to address where they cover thefollowing topics:
How Internet is changing how we communicate (messaging)
in electronic form, leaving behind the use of means such as
fax and phone.

The form of advertising as an electronic competition.
The great changes that arise in business or businesses with
the advent of Internet, since they are all looking to be more
profitable and competitive almenor cost.
Education with new patterns of teaching (classrooms,
libraries and bookstores) with opportunities for further
studies.
The wide variety of services to which you can apply this tool.
1.Definition of InternetInternet is a group of networks of communication that use
the protocol TCP/IP, the protocol TCP/IP warrants that
the varieties of physical networks work as a single logical
network.
The origin of the Internet
goes back at least to 1969,
when the first connectionof computers known as
ARPANET was established
between 3 Universities in
California and 1 in Utah,
United States.
Internet has mostly impact
in the work; leisure andthe way of get the
information around the
world.
8/6/2019 Conversacion II

Thanks to the Internet, thousands of people can access to
the information immediately, download music, films,
games, etc.
Internet is the most important tool. Nowadays, we cansurf on internet to find mew friends, information, send e-
mails, sharing files, etc.
Comparing the traditional encyclopedias and libraries with
Internet, it is a revolution.
There are other services on internet such as e-mail, FTP,
chats, VoIP, games online, etc.
The most successful service on Internet is The WWW.
The people often confuse the WWW with Internet, but
they arent the same, The WWW uses Internet like a way
of transmission of data.
2.What doesWWW mean?www = World Wide Web", the network" or simply "The
Web", as is commonly known, is basically a media text,
graphics and other multimedia objects over the Internet,
that is, the web is a hypertext system that uses Internet
as its transport mechanism or from another point of view,
a graphical way to browse the Internet.
Founded in 1989 in a Swiss research institute, the web
based search engine and hypertext transport protocol
(hypertext transport protocol (http)). Most Web
documents are created using HTML (hypertext markup
language).
8/6/2019 Conversacion II
7/14
It is important to know that www is not synonymous with
the Internet; the Web is a subset of the Internet that
consists of pages that can be accessed using a
browser. Internet is the network of networks where the
information resides. Both e-mail, and FTP, games and
more are part of the Internet, but not the World Wide
Web.
To find hypertext use
programs called Web
browsers that retrieve
pieces of information
(called "documents" or
"sites") web server and
displayed on the computer
screen of the person you are
looking for graphic information, video and textual even
audio.
Then you can follow links and hyperlinks on each page to
other documents or return information to the server to
interact with it. The act of following a link after another
is sometimes called surfing the Web.
The web has become a very popular medium to publish
information on the Internet, and the development ofsecure transfer protocol (secured server protocol (https)),
the web is now a means of electronic commerce where
consumers can choose their products online and make
purchases using the bank card information securely.

3.WWW PREFIXMany domain names used for the World Wide Web begin
with wwwbecause of the long-standing practice of naming
Internet hosts (servers) according to the services theyprovide. The hostname for a web server is often www, in
the same way that it may be ftp for an FTP server,
andnews or nntp for a USENET news server. These host
names appear as Domain Name
System (DNS) subdomain names, as in www.example.com.
The use of 'www' as a subdomain name is not required by
any technical or policy standard; indeed, the first everweb server was called nxoc01.cern.ch, and many web
sites exist without it. Many established websites still use
'www', or they invent other subdomain names such as
'www2', 'secure', etc. Many such web servers are set up
such that both the domain root (e.g., example.com) and
the wwwsubdomain (e.g., www.example.com) refer to
the same site; others require one form or the other, orthey may map to different web sites.
The use of a subdomain name is useful for load
balancing incoming web traffic by creating a CNAME
record that points to a cluster of web servers. Since,
currently, only a subdomain can be cname'ed the same
result cannot be achieved by using the bare domain root.
When a user submits an incomplete website address to a
web browser in its address bar input field, some web
browsers automatically try adding the prefix "www" to the
beginning of it and possibly ".com", ".org" and ".net" at the
end, depending on what might be missing. For example,
8/6/2019 Conversacion II
9/14
entering 'microsoft' may be transformed
to http://www.microsoft.com/ and 'openoffice'
to http://www.openoffice.org. This feature started
appearing in early versions of Mozilla Firefox, when it still
had the working title 'Firebird' in early 2003. It is reported
that Microsoft was granted a US patent for the same idea
in 2008, but only for mobile devices.
The scheme specifier (http:// or https://) in URIs refers
to the Hypertext Transfer Protocol and to HTTP
Secure respectively and so defines the communication
protocol to be used for the request and response. TheHTTP protocol is fundamental to the operation of the
World Wide Web, and the encryption involved in HTTPS
adds an essential layer if confidential information such as
passwords or banking information are to be exchanged
over the public Internet. Web browsers usually prepend
the scheme to URLs too, if omitted.
4.EVOLUTION OF THE WWW4.1.WEB 1.0
The Web 1.0 (1991 - 2003) is the way more basic,
where the web navigators are only text, and they are
very fast. Later HTML code appear, it made the web
pages more pleasant to the eyes, in the same way
the first visual navigators such as Internet Explorer,Netscape, etc.
The Web 1.0 is only reading, the user cant interact
with the content of the page, it is limited to the
Webmaster.
8/6/2019 Conversacion II
10/14
Some typical design elements of a Web 1.0 site
include:
Static pages instead of dynamic user-generatedcontent
he use of tables to position and align elements ona page.
HTML forms sent via email. A user would fill in aform, and upon clicking submit their email
client would attempt to send an email containing
the form's details
4.2.WEB 2.0The term Web 2.0 (2004 - Now) is commonly
associated with a social phenomenon; it is based in
the interaction of different applications in the web
to share information, the interoperability, the design
concentrate on
the user and t he
collaboration inthe World Wide
Web.
A web site 2.0
allows to the users
to interact with
other users or to
change thecontents of the web site.
A Web 2.0 site gives its users the free choice to
interact or collaborate with each other in a social
8/6/2019 Conversacion II
11/14
media dialogue as creators (prosumer) of user-
generated content in a virtual community, in
contrast to websites where users (consumer) are
limited to the passive viewing of content that was
created for them
Web 2.0 websites allow users to do more than just
retrieve information. By increasing what was already
possible in "Web 1.0", they provide the user with
more user-interface, software and storage facilities,
all through their browser. This has been
called "Network as platform"computing. Users can
provide the data that is on a Web 2.0 site and
exercise some control over that data. These sites
may have an "Architecture of participation" that
encourages users to add value to the application as
they use it.
The client-side/web browsertechnologiestypically used inWeb 2.0development areAsynchronousJavaScript and XML(Ajax), AdobeFlashand the AdobeFlex framework,and JavaScript/Ajax frameworks suchas Yahoo! UI Library, Dojo Toolkit, MooTools,
8/6/2019 Conversacion II
12/14
and jQuery. Ajax programming uses JavaScript toupload and download new data from the web serverwithout undergoing a full page reload.
To allow users to continue to interact with the page,communications such as data requests going to theserver are separated from data coming back to thepage (asynchronously). Otherwise, the user wouldhave to routinely wait for the data to come backbefore they can do anything else on that page, justas a user has to wait for a page to complete thereload. This also increases overall performance of thesite, as the sending of requests can complete quicker
independent of blocking and queueing required tosend data back to the client.
Examples of Web 2.0 are the web community, the
web services, the web applications, the wikis, and
blogs.
A WIKI: is a website that allows the easy creation andediting of any number of interlinked web pages viaa web browser using a simplified markup language ora WYSIWYG text editor.
Wikis are typically powered by wiki software and areoften used to create collaborative wiki websites, topower community websites, for personal note taking,
in corporate intranets, and in knowledgemanagementsystems.
Wikis may exist to serve a specific purpose, and insuch cases, users use their editorial rights to removematerial that is considered "off topic." Such is thecase of the collaborative encyclopedia Wikipedia.

http://en.wikipedia.org/wiki/Wiki - cite_note-Britannica-1#cite_note-Britannica-1 Incontrast, open purpose wikis accept content withoutfirm rules as to how the content should be organized.
4.3.WEB 3.0Web 3.0 is a
neologism used to
describe the evolution
of the use and interaction in the network through
different paths. This includes the transformation of
the network in a database, a move towards making
content accessible by multiple non-browser
applications, the thrust of artificial intelligence
technologies, Semantic Web, Geospatial Web, or Web
3D
The Web 3.0 technologies such as intelligent
software, which uses semantic data, have been
implemented and used in small-scale companies to
achieve more efficient data handling. In recent
years, however, more focus has been directed to
transfer these technologies semantic intelligence to
the general public.

5.CONCLUSIONS In Web 1.0 the user had access to information only as
a receiver, did not have the opportunity to
participate in the content, the pages were static,
generally only of text and few images, and HTML
format was used.
Another possible path for the Web 3.0 is the directionin 3D vision. This would involve transforming the Web
into a series of 3D spaces, taking further the concept
proposed by Second Life. This could open new ways
to connect and collaborate, using three-dimensional
spaces.
The number of users increases continuously. In 2006,the number of Internet users estimated at 1,100
million. By 2016 it is estimated that the number will
rise to 2,000 million.
