It serves as a user interface to display web pages, multimedia, and other online resources. Let us understand here how a web browser generally works (how an internet browser works).

use input

When you open a web browser and enter a URL (Uniform Resource Locator) or click on a link, you are providing input to the browser.

url parsing

The browser parses the URL to extract information such as the protocol (http, https), the domain name (eg,, and the path to a specific resource on the server.

dns resolution

The browser sends a Domain Name System (DNS) request to a DNS server to translate the domain name into an IP address. This is necessary because computers communicate over IP addresses, not domain names.

establish connection

The browser uses the IP address obtained from DNS to establish a connection with the web server hosting the requested resource. This connection is usually established using HTTP (Hypertext Transfer Protocol) or its secure version, HTTPS.

HTTP request

The browser sends an HTTP request to the web server. This request includes the request type (GET, POST, etc.), headers, and other relevant information.

web server processing

The web server receives the request, processes it, and generates the appropriate response. This response typically includes the HTML content of the requested web page, as well as other resources such as images, stylesheets, scripts, and more.

HTML parsing and rendering

Browser (Internet Browser) gets the response, especially the HTML content of the web page. It then parses the HTML code to understand the structure of the page, its elements and their relationships.

resource fetching

As the browser parses the HTML, it finds references to other resources such as images, stylesheets, and scripts. It fetches these resources from the server using additional HTTP requests.


The browser renders web pages using a combination of HTML structure, CSS styles, and JavaScript interactions. It draws visible elements on the screen, following the Document Object Model (DOM) and the CSS box model.

javascript execution

If a web page contains JavaScript code, the browser’s JavaScript engine executes it. JavaScript can manipulate the page content, interact with the user, and perform different actions.

user interaction

Users can interact with the rendered web page by clicking on links, filling out forms and taking other actions.


Browsers may store some resources locally in the cache. This permits faster loading times when revisiting a website because the browser can retrieve cached resources without making additional server requests.


Browsers also play an important role in ensuring security. They implement security protocols such as HTTPS to encrypt data transmission and warn users about potentially malicious websites.

cookie management

Browsers manage cookies, which are small pieces of data that websites use to store users’ information and preferences. Overall, a web browser is responsible for retrieving, presenting, and presenting web content to users, enabling them to navigate the vast landscape of the Internet.
