View source for Web browser

__NOTOC__
A web browser is a software application for retrieving and presenting information resources found on the [[web|World Wide Web]].

==Retrieving information==
The browser's first task is to find and retrieve the desired information resource. Each information resource on the [[web]] is identified by a [[Uniform Resource Identifier]] (URI) and located by a [[Uniform Resource Locator]] (URL). When the URL is entered into the browser's [[address bar]], the browser sends a request to the [[website]]. The request is processed and answered by the [[web server]] running the website, which sends a copy of the corresponding information resource to the brower.

The retrieved information resource may be a [[web page]], image, video, or any other identified piece of content on the [[website]].

In addition to accessing resources on the [[web|World Wide Web]], web browsers can also retrieve and read any information sources in HTML format, such as files located on the user's own computer, or on servers in private networks.

==Presenting information==
The web browser reads the accessed information source, written in [[HTML|HyperText Markup Language]] (HTML), and prepares it for display it on the user's screen.

==Navigation via hyperlinks==
Information resources on the web typically contain [[hyperlink]]s pointing to related resources. Clicking on the hyperlink will direct the web browsers to the related resource, thus allowing users to "navigate" from link to link. Browsers generally also include a back-arrow allowing navigation back to previously-read pages.

Early browsers could only open one information resource (or page) at a time. More recent browsers can open several resources at a time, either in separate [[window]]s, or in separate [[tab]]s.

*Internet Explorer
