close this phase of navigation in the infinite network of networks, which could experience a real pleasure derived from the endless pursuit of knowledge, addressing worldly issues, dissimilar and varied, exercise had no been possible without the indispensable and irreplaceable help of four pillars:
lot Internet: the World Wide Web or Global Network World
• Windows INTERNET EXPLORER: the most used web browser
· GOOGLE: the most important Search Engine
· WIKIPEDIA: The biggest multilingual free encyclopedia ever written.

INTERNET arises in the United States in the sixties of the twentieth century, to support its military, was initially used by the government, universities and other academic centers, but today it is constituted an unprecedented revolution in the world of computing and communications, because the effect of ecumenism, allows the spread of information, regardless the geographic location of their users, allowing global communication flow on a scale unprecedented in human history.
decentralized Internet is a collection of interconnected communication networks, which has a profound impact on work, leisure and knowledge worldwide, allowing sudden and extreme decentralization of information and data, making a tool for mass rapid globalization and integration in the human life. Internet as such, has no body that governs.
The World Wide Web or World Global Network is a set of documents I hypermedia hypertext, linked and accessible via the Internet, is a set of protocols that allows a simple, remote consultation hypertext files.
The web structure based on links and unique way, was created in 1989 by Englishman Sir Timothy "Tim" John Berners-Lee and the Belgian Robert Cailliau in Geneva, Switzerland, but it was not until 1992 that was published debuting the web as a public service by joining hypertext and the Internet, announcing the April 30, 1993 that the Web would be free for everyone. Basically, Tim, the father of the Web, developed the ideas of the three Internet standards: HTML, HTTP and URL.
Research by the American scientist Vinton "Vint" Cerf G. in 1972, led the design of the TCP / IP (Transmission Control Protocol / Internet Protocol) or computer language used on the Internet.
The Web- English- network is through greater dissemination of personal exchange appeared in the history of humanity, far ahead of print, it is a social and technological revolution.
Viewing a web page the World Wide Web starts typing the URL of the page in the web browser or by following a hypertext link to that page or resource. URL (Uniform Resource Locators) - in Castilian, the Uniform Resource Locator- is one of the three main standards of the Web.
The first step is to translate the server name of the URL to an IP address using the distributed database on the Internet, known as DNS.
The next step is to send an HTTP (Hypertext Transfer Protocol )-Text Transfer Protocol- the Web server requesting the HTML (Hypertext Markup Language )-Hypertext Markup Language, " which are the two main standards of the Web.
a user views web pages, which can contain text, images, videos and other multimedia content, and navigate through them using hyperlinks, through a Web browser.
The most widely used web browser since 1999, is the Windows Internet Explorer developed by Microsoft since 1994 by Thomas Reardon and perfected by Benjamin Slivka for its implementation in Windows 95. Its latest version is 8.0, which is freely available.
Thomas Reardon was 21 when Bill Gates offered him a senior position at Microsoft, in 1991. Ben is applied as a mathematician at the University of Northwestern.
Internet Explorer stores temporary Internet files to allow faster access (or access outside line) to previously visited pages.
uses a componentized architecture on the "Component Object Model (COM). It consists of five main components:
- Wininet.dll, manager of HTTP and FTP protocol. It handles all network communications protocols.
- Urlmon.dll, responsible for handling MIME-based content and web content downloads.
-
MSHTML.dll houses the Trident rendering engine, which is responsible for displaying pages on the display and management of the "Documents object model" of web pages. It analyzes the HTML / CSS files and creates the internal DOM representation. It also exposes a set of APIs for runtime inspection and modification of the DOM tree. -
Shdocvw.dll provides navigation, local storage and functionality to the browser. -
Browseui.dll, head of the browser user interface, including the framework of graphical user interafaz ("chrome"), housing all the menus and toolbars. Internet Explorer remains the dominant browser.
to store Web content requires a browser. The ultimate search engine is GOOGLE, a name derived from googol- which represents 10 raised to 100 - and glasses-goggles . Based on technology- PageRank determines the importance of each page- two PhD students in Computer Science from Stanford University, Lawrence Edward "Larry Page, born in 1972 in East Lansing, Michigan, United States, Jewish, and Sergey Brin, born in 1973 in Moscow, Russia, begin to create an algorithm for search data, which would become the heart that powers Google.
These two computer geniuses founded in 1998 in Menlo Park, California, the company Google, which offers a quick and easy way to find information on the Web. Currently Google is headquartered in Mountain View, California, with a search engine with access to an index of over 8, 168 million Web pages that can respond daily to more than 200 million hits.
search engine also has created other Web sites like Google Images, Google Groups, Google Directory, Google News. It also has additional services as Gmail, Google Video, Google Maps, Google Earth, "Adsense, Adwords, Google Calendar and Google Notebook. You Tube is owned by Google since 2006.
also offers tools: Google Toolbar, Google Desktop, Picasa and Google Print.
Most online encyclopedia written by volunteers, is Wikipedia -name portmanteau formed by the contraction- the words wiki - Hawaiian for "quick and pediatricians of paideia, education, classical Greek, is a collaborative effort to create a free encyclopedia, free and accessible to all; is currently the largest and most popular online reference work, with more than 12 million items.
Wikipedia was launched in January 2001 by the American Jimmy "Jimbo" Wales and Donald Lawrence "Larry" Mark Sanger. Jimbo, born in 1966 in Huntsville, Alabama, graduated from Auburn and Alabama, he earned his doctorate at the University of Indiana. Larry, from the state of Washington and raised in Anchorage, Alaska, graduated from Reed College and a doctorate from Ohio State University. WIKIPEDIA
in perpetual development, has its headquarters in San Francisco, California, but its participants from around the world, trying to build more items comprehensive as possible. It has a small number of paid employees -23 - and a global community of more than 150000 volunteers dedicated to sharing knowledge freely for eight years they have contributed more than eleven million articles in 265 languages over 275 million monthly visitors, who access free at no charge and without advertising. Anyone can freely use Wikipedia content for any purpose.
Wikipedia receives between 10000 and 30 000 requests for pages per second, 3.1% from Mexico. Its sister projects Wiktionary, Wikibooks, Wikiversity, Wikiquote, Wikinews, Wikisource, Wikimedia Commons, and Meta-Wiki Wikispecies

The title of this post evokes the past moment in which a doctor with a strange mixture of resignation, nostalgia and compliance, "exclaimed those words in the act that gave me an address Mexico's federal government. I'm experiencing that same feeling at the end of the cycle THE PLEASURE OF THE SEARCH.
