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.


5/14

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.


6/14

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).


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,


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.


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


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,


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.


13/14

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.


14/14

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.
