Web browser

A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content.^[1] Hyperlinks present in resources enable users to easily navigate their browsers to related resources.
Although browsers are primarily intended to access the World Wide Web, they can also be used to access information provided by Web servers in private networks or files in file systems. Some browsers can be also used to save information resources to file systems.

History

Main article: History of the web browser

WorldWideWeb for NeXT, released in 1991, was the first web browser.^[2]

The history of the web browser dates back in to the late 1980s, when a variety of technologies laid the foundation for the first web browser, WorldWideWeb, by Tim Berners-Lee in 1991. That browser brought together a variety of existing and new software and hardware technologies.

The introduction of the NCSA Mosaic web browser in 1993 – one of the first graphical web browsers – led to an explosion in web use. Marc Andreessen, the leader of the Mosaic team at NCSA, soon started his own company, named Netscape, and released the Mosaic-influenced Netscape Navigator in 1994, which quickly became the world's most popular browser, accounting for 90% of all web use at its peak (see usage share of web browsers).

Microsoft responded with its browser Internet Explorer in 1995 (also heavily influenced by Mosaic), initiating the industry's first browser war. By bundling Internet Explorer with Windows, Microsoft was able to leverage its dominance in the operating system market to take over the web browser market; Internet Explorer usage share peaked at over 95% by 2002.^[3] Internet Explorer has 65% browser usage share as of October 2009 according to Net Applications.^[4]

Opera debuted in 1996; although it has never achieved widespread use, having 2% browser usage share as of October 2009,^[4] it has a substantial share of the fast-growing mobile phone web browser market, being preinstalled on over 40 million phones. It is also available on several other embedded systems, including Nintendo's Wii video game console.

In 1998, Netscape launched what was to become the Mozilla Foundation in an attempt to produce a competitive browser using the open source software model. That browser would eventually evolve into Firefox, which developed a respectable following while still in the beta stage of development; shortly after the release of Firefox 1.0 in late 2004, Firefox (all versions) accounted for 7.4% of browser use.^[3] As of October 2009, Firefox has a 24% usage share.^[4]

Apple's Safari had its first beta release in January 2003; as of October 2009, it has a dominant share of Apple-based web browsing, accounting for just over 4% of the entire browser market.^[4] Its rendering engine, called WebKit, is also running in the standard browsers of several mobile phone platforms, including the iPhone OS, Google Android, Nokia S60 and Palm WebOS.

The most recent major entrant to the browser market is Google's WebKit-based Chrome, first released in September 2008. As of October 2009, it has a 4% usage share.^[4]

Function

The primary purpose of a web browser is to bring information resources to the user. This process begins when the user inputs a Uniform Resource Identifier (URI), for example http://en.wikipedia.org/, into the browser. The prefix of the URI determines how the URI will be interpreted. The most commonly used kind of URI starts with http: and identifies a resource to be retrieved over the Hypertext Transfer Protocol (HTTP). Many browsers also support a variety of other prefixes, such as https: for HTTPS, ftp: for the File Transfer Protocol, and file: for local files. Prefixes that the web browser cannot directly handle are often handed off to another application entirely. For example, mailto: URIs are usually passed to the user's default e-mail application, and news: URIs are passed to the user's default newsgroup reader.

In the case of http, https, file, and others, once the resource has been retrieved the web browser will display it. HTML is passed to the browser's layout engine to be transformed from markup to an interactive document. Aside from HTML, web browsers can generally display any kind of content that can be part of a web page. Most browsers can display images, audio, video, and XML files, and often have plug-ins to support Flash applications and Java applets. Upon encountering a file of an unsupported type or a file that is set up to be downloaded rather than displayed, the browser prompts the user to save the file to disk.

Information resources may contain hyperlinks to other information resources. Each link contains the URI of a resource to go to. When a link is clicked, the browser navigates to the resource indicated by the link's target URI, and the process of bringing content to the user begins again.

Cloud Myths Dispelled

Based on
Changing the default locale is a little different on Ubuntu that in other Distros:


To check which locale you currently have as your default just run:  
locale

Add the locale to the list of 'supported locales'
Edit /var/lib/locales/supported.d/local and add the following line:
es_BO ISO-8859-1

Regenerate the supported locales
Run sudo dpkg-reconfigure locales

Change the default locale
Edit /etc/environment or /etc/default/locale and ensure the LANG and LANGUAGE lines read as follows:
LANG="es_BO"
LANGUAGE="es_BO:es"

Reboot!

Rerun locale to check that your default locale is now es_BO

Open Source and the Web

The Web is overwhelmingly open source, as Lotus founder Mitch Kapor states:

The accomplishment of open source is that it is the back end of the Web, the invisible part, the part that you don't see as a user.
All of the servers, pretty much, they run Linux as the operating system; they run Apache as the basic Web server on top of which everything else is built. The main languages out of which Web applications are built - whether it's Perl or Python or PHP or any of the other languages - those are all open source languages. So the infrastructure of the Web is open source ... the

Web as we know it is completely dependent on open source.
