Web page is the part of world wide web so we use web browser for the excess !

Web browser

A web browser is a client software application that is used to request and display web pages. It allows users to access and interact with information on the World Wide Web.

Requesting Web Pages
When a user enters a URL (Uniform Resource Locator) or clicks on a link, the web browser sends a request to the appropriate web server for the corresponding web page. The request is sent using the HTTP (Hypertext Transfer Protocol) or HTTPS (Hypertext Transfer Protocol Secure) protocol.

Displaying Web Pages
Once the web browser receives the requested web page from the web server, it processes the HTML (Hypertext Markup Language) code and renders the page for the user to view. The browser interprets the HTML tags and displays the text, images, videos, and other multimedia elements according to the instructions provided in the code.

Rendering HTML
The web browser parses the HTML code and constructs a Document Object Model (DOM) tree, which represents the structure of the web page. It then applies the CSS (Cascading Style Sheets) styles to the elements in the DOM tree, determining the layout, colors, fonts, and other visual aspects of the page. Finally, the browser renders the web page by displaying the formatted content to the user.

Interacting with Web Pages
Web browsers also provide various features and functionalities that allow users to interact with web pages. These include:

1. Hyperlinks: Users can click on hyperlinks to navigate to different web pages within the same website or to external websites.

2. Forms: Web forms allow users to input data and submit it to web servers for processing. Examples of forms include login forms, contact forms, and search boxes.

3. Cookies: Web browsers store cookies, which are small text files, on the user's computer. These cookies can be used to remember user preferences, track user activity, and provide personalized content.

4. Bookmarks: Users can save the URLs of web pages they frequently visit as bookmarks for quick access.

5. Extensions and Plugins: Web browsers support extensions and plugins that enhance their functionality. These can include ad blockers, password managers, video players, and more.

In conclusion, a web browser is a client software that allows users to request and display web pages by sending HTTP or HTTPS requests to web servers and rendering the HTML code received. It also provides features for interacting with web pages and customizing the browsing experience.
