The Web browser is composed of a renderer, a user interface and incidentally an extensions manager for plugins.
For the vast majority of browsers on the market, the user interface consists of a display area managed as tabs, a drop down menu bar, a toolbar and a status bar.
The bar menu features favorites (or bookmarks), controls files (open, closed), configuration options, etc..
The primary function of a web browser is to consult information available (“resource” in the terminology of the Web) on the World Wide Web. The main stages of the consultation of a resource are:
The user gives the Web browser the web address of the resource to consult. There are three ways to give a web address:
type in the web address bar of the browser address;
choose a resource from the list of favorites (or bookmark this page or bookmark), knowing that each is associated with a favorite web address;
follow a hyperlink, knowing that each link is associated with a web address.
The browser connects to the Web server hosting the target resource and downloads. The communication protocol commonly used is HTTP.
the rendering engine of the browser treats this resource, downloads any associated resources, and displays the result on the screen of the user.
