A web browser is a application software  for retrieving and presenting and traversing information resources on the world wide web.An information resource is identified by a Uniform Resource Identifier(URL/URI) and may be a web page,image,video or other piece of content.Hyperlink presents in resources enable users easily to  navigate their browser to related resources

The first browser , called World Wide Web(w w w),was created in 1990.That browsers name was changed to Nexus to avoid confusion with the developing information space known as the World Wide Web.The first browser in graphical interface was mosaic, which appeared in 1993 and "the world's first popular browser"which made the World Wide Web system easy to use and more accessible to the average person.Many of the user interface features in Mosaic went into Netscape Navigator.

    Microsoft responded with its INTERNET EXPLORER in 1995, also heavily influenced by Mosaic, initiating the industry's first browser war.Bundled with Windows , Internet Explorer gained dominance in the web browser market; Internet Explorer usage share peaked at over 95% by 2002.

OPERA debuted in 1996; it has never achieved widespread use, having less than 2% browser usage share as of February 2012 according to Net Applications.[7] Its Opera-mini version has an additive share, in April 2011 amounting to 1.1% of overall browser use, but focused on 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 Nintedo's wii video game console.

Apple's  SAFARI had its first beta release in January 2003; as of April 2011, it had a dominant share of Apple-based web browsing, accounting for just over 7% of the entire browser market

In 1998, Netscape launched what was to become the MOZHILLA 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% of browser use. As of August 2011, Firefox has a 28% usage share.

The most recent major entrant to the browser market is Chorme,first released in September 2008. Chrome's take-up has increased significantly year by year, by doubling its usage share from 8% to 16% by August 2011. This increase seems largely to be at the expense of Internet Explorer, whose share has tended to decrease from month to month.[8] In December 2011, Chrome overtook Internet Explorer 8 as the most widely used web browser but still had lower usage than all versions of Internet Explorer combined.[9] Chrome's user-base continued to grow and in May 2012, Chrome's usage passed the usage of all versions of Internet Explorer combined.[10] By April 2014, Chrome's usage had hit 45%.

Available web browsers range in features from minimal, text-based user interfaces with bare-bones support for HTML to rich user interfaces supporting a wide variety of file formats and protocols. Browsers which include additional components to support e-mail,Uesnet  news, and Internet Relay Chat(IRC), are sometimes referred to as "Internet suites"rather than merely "web browsers.

Furthermore, most browsers can be extended via plug-ins,downloadable components that provide additional features.

User interface

        Most major web browsers have these user interface elements in common:

  • Back and forward buttons to go back to the previous resource and forward respectively.
  • A refresh or reload button to reload the current resource.
  • A stop button to cancel loading the resource. In some browsers, the stop button is merged with the reload button.
  • An address bar to input the Uniform Resource Identifier (URI) of the desired resource and display it.
  • A search bar to input terms into a search engine, In some browsers, the search bar is merged with the address bar
  •   A  status bar to display progress in loading the resource and also the URI of links when the cursor hovers over them, and page zooming capability.
  • The viewport, the visible area of the webpage within the browser window.
  • The ability to view the HTML source for a page.
