What is the Difference Between Web Server and Web Browser?

🆚 Go to Comparative Table 🆚

The main difference between a web browser and a web server lies in their functions and purposes.

A web browser is an application software used for browsing and displaying web pages on the internet. Examples of web browsers include Google Chrome, Internet Explorer, and Mozilla Firefox. Browsers request web documents and services from web servers, which are then displayed to the user.

A web server, on the other hand, is a software or computer that provides various services and web documents to clients (i.e., web browsers). When a browser requests a web page, the web server accepts, approves, and responds to the request, sending the web content back to the browser. If the server cannot find the requested page, it sends an error message (e.g., Error 404 – page not found) to the browser. Web servers host websites and their supporting files, making them accessible to users through their browsers.

In summary:

  • A web browser is a user-facing application that requests and displays web pages from web servers.
  • A web server is a software or computer that hosts websites and provides web documents and services to web browsers.

Comparative Table: Web Server vs Web Browser

Here is a table that highlights the differences between a web browser and a web server:

Parameter Web Browser Web Server
