What Is a Web Server Give an Example?


Larry Thompson

A web server is a crucial component of the World Wide Web that enables the delivery of web pages and other content to users. It acts as a mediator between the client (web browser) and the server-side resources, ensuring that the requested information is delivered accurately and efficiently.

What Is a Web Server?
A web server is a software application or hardware device that hosts websites, web applications, or any other web content. It receives HTTP/HTTPS requests from clients and responds by serving the requested files or executing server-side scripts.

How Does a Web Server Work?
When you type a URL into your web browser, it sends an HTTP request to the appropriate web server. The server processes this request using various protocols and technologies to retrieve the requested information. Once the processing is complete, the server sends back an HTTP response containing the requested data, which is then displayed by your browser.

Example of a Web Server: Apache HTTP Server

There are several popular web servers available today, each with its own unique features and advantages. One such example is the Apache HTTP Server.

Apache HTTP Server (commonly known as Apache) is an open-source web server software developed by the Apache Software Foundation. It is one of the most widely used web servers due to its stability, flexibility, and extensibility.

Features of Apache:

  • Modularity: Apache allows users to extend its functionality through modules. These modules can be added or removed depending on specific requirements.
  • Virtual Hosting: With Apache, you can host multiple websites on a single physical machine by configuring virtual hosts.
  • Security: Apache provides numerous security features such as SSL/TLS encryption and support for various authentication methods.
  • Performance: It offers efficient resource utilization and can handle a large number of concurrent connections.
  • Platform Independence: Apache is platform-independent and can run on various operating systems, including Windows, Linux, and macOS.

Installing Apache on Ubuntu:

To install Apache on an Ubuntu server, follow these steps:

  1. Open a terminal window.
  2. Type the following command to update the package index:
    $ sudo apt update
  3. Install Apache by running the following command:
    $ sudo apt install apache2
  4. Once the installation is complete, you can start, stop, or restart the Apache service using the following commands:
    • To start:
      $ sudo systemctl start apache2
    • To stop:
      $ sudo systemctl stop apache2
    • To restart:
      $ sudo systemctl restart apache2

Note: The above steps are specific to Ubuntu. For other operating systems, the installation process may vary. Make sure to refer to the official documentation for your specific environment.


In summary, a web server plays a crucial role in serving web content to users. It acts as an intermediary between clients and server-side resources.

The Apache HTTP Server is one such example of a powerful and widely used web server that offers various features and benefits. By understanding how web servers work and exploring different examples, you can gain a deeper understanding of the web development ecosystem.
