A web browser is a computer program used for accessing the World Wide Web. A web browser retrieves and renders webpages to display information stored on a web server. The browser sends an HTTP request to the server, which responds with the requested file. Most web pages are written in HTML, a markup language which allows inclusion of other files; the browser interprets the file and makes additional requests of the server for the additional files, then interprets and displays the results for the user.
Most browsers today are capable of displaying text in HTML, with formatting specified in CSS, images in JPEG, GIF, and PNG formats, scripts written in javascript, animations written in Macromedia's Flash language, and applets written in Java.
Popular Browsers
Internet Explorer
The most popular web browser today is Internet Explorer from Microsoft.[1] Internet Explorer has come bundled with every version of Microsoft's Windows operating system since Windows 95, and is supplied free of charge. Microsoft created versions of Internet Explorer for the Macintosh, Solaris and HP-UX operating systems[2], but has ceased development on all three versions.[3] The most recent official version is Internet Explorer 7, although Internet Explorer 6 is still supported with Microsoft's extension of Windows XP support until sometime midyear 2008.
Mozilla Firefox
Mozilla Firefox is the second-most popular web browser today.[1] It is the second browser to result from the open-source Mozilla Project started by Netscape corporation to develop a new browser to succeed the Netscape Communicator suite. Versions of Mozilla Firefox are available for the Windows, Macintosh, and Linux operating systems; additionally, as the browser is open-source, volunteers have ported it to Solaris and OS/2.
Safari/Konqueror
Safari is a browser developed by Apple, originally only for its Mac OS X operating system but now also for Windows. It was the first browser to pass the W3C's Acid2 rendering compatibility test, is currently the third most used.[1] Apple's rendering engine, WebKit, is a fork of KHTML, the open source engine developed for the Konqueror web browser, which is part of the KDE project for Linux and Unix. WebKit is open source, and the changes are back-ported to KHTML.
Opera
The Opera web browser is a browser initially developed by Telenor of Norway. The developers formed Opera Software, and released version 2.1 publicly in 1997, at version 2.1. Until 2005, Opera was sold for approximately $25 to $35, though an ad-supported version had appeared earlier for users who did not wish to pay. Since then, it has been available for free.[4] Opera had an early lead in compliance with the CSS standard, and claims to be more standards-compliant than its competitors. Versions of Opera for mobile devices are the default browsers on several mobile phones. Other versions have been developed for video gaming consoles such as the Nintendo Wii.
History
Tim Berners-Lee on the creation of the web
The very first web brower was a program named WorldWideWeb, developed on a NeXT computer, and released in March 1991. Several other browsers were developed in the subsequent two years, but the most important new browser was NCSA Mosaic, developed by Marc Andreessen and Eric Bina from the NCSA, released in February 1993 on Unix, and later that year for the Macintosh (computer).[5] The 2.0 version of Mosaic, released in January 1994, was the first browser to actually show images embedded in the text, rather than in a separate window.[6]
Other browsers, current and historical
Netscape Navigator was the first browser to gain widespread usage, and was developed for a variety of platforms, including Windows and the Macintosh. In response to competition from Microsoft Internet Explorer, it was ultimately distributed with a newsreader, HTML editor, and other features. However, it steadily lost market share. Its codebase was later spun into an open source project called Mozilla, which is is the ancestor of Firefox.
Mozilla
Mozilla is a open-source browser developed from a Netscape codebase. It was the precursor to Mozilla Firefox.
HotJava
HotJava was a browser developed by Sun Microsystems, designed as a proof-of-concept for the Java programming language. The browser was written entirely in Java, and ran Java applets natively.
Omniweb
Omniweb is a browser developed for Mac OS X.
Camino
Camino is an alternative version of Firefox for Mac OS X, made to conform more closely to the Macintosh's interface conventions.
