Functions of Web Browsing

[Kale Deepika]

can anybody explain me the functions of Web Browsing?

[Gulshan Kumar Pahwa]

The primary purpose of a web browser is to bring information resources to the user. This process begins when the user inputs a URL for example http://lislinks.com  into the browser. The prefix of the URL determines how the URL will be interpreted. The most commonly used kind of URL starts with HTTP: and identifies a resource to be retrieved over the HTTP. Many browsers also support a variety of other prefixes such as FTP: for file transfer protocol and File: for local files. Prefixes that the web browser cannot directly handle are often handed of to another application entirely.


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.
