A web browser (commonly known as a browser) is a software application to retrieve, present, and traverse information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI / URL) that can be a web page, image, video, or other piece of content. Hyperlinks in resources allow users to easily navigate their browsers to related resources.
Although browsers are primarily intended to use the World Wide Web, they can also be used to access information provided by web servers on private networks or files on file systems. The most popular web browsers are Chrome, Edge (preceded by Internet Explorer), Safari, Opera and Firefox. The main purpose of a web browser is to bring information resources to the user ("recovery" or "recovery"), allowing them to view the information ("display", "render") and then access other information links "). This process begins when the user enters a URL (Uniform Resource Locator), for example http://en.wikipedia.org/, in the browser. The URL prefix, the Uniform Resource Identifier or URI, determines how the URL will be interpreted. The most commonly used URI type begins with http: and identifies a resource to be retrieved through the Hypertext Transfer Protocol (HTTP). Many browsers also support a variety of other prefixes, such as https: for HTTPS, ftp: for file transfer protocol and file: for local files. Prefixes that the web browser can not handle directly are often delivered to another application completely. For example, mailto: URIs are usually passed to the user's default email 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 show it. HTML and associated content (image files, format information such as CSS, etc.) are passed to the browser's design engine to transform it from an interactive document, a process known as rendering. Apart from HTML, web browsers can usually display any type of content that may be part of a web page. Most browsers can display images, audio, video, and XML files, and often have add-ons to support Flash applications and Java applets. When you find a file of an unsupported type or a file that is set to be downloaded instead of being 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 destination URI of the link and the process of bringing content to the user starts again. |
