For What Purpose Web Server Is Used?

A web server is a crucial component of the World Wide Web. It serves as a platform that allows websites to be accessed by users over the internet. When you type a website address in your browser and hit enter, the web server retrieves and delivers the requested web page to your device.

But what exactly is the purpose of a web server? Let’s dive in and explore its various uses.

1. Hosting Websites

One of the primary purposes of a web server is to host websites. It stores website files, such as HTML, CSS, JavaScript, images, and videos, and delivers them to visitors when they request a particular URL.

These files are stored on the server’s hard disk or other storage devices.

Web servers support various types of websites:

  • Static Websites: These websites consist of fixed content that doesn’t change unless manually updated. The web server simply retrieves and serves these files as they are.
  • Dynamic Websites: Dynamic websites generate content on-the-fly based on user input or database queries.

    The web server interacts with other software components such as databases and scripting languages to generate dynamic pages.

  • E-commerce Websites: E-commerce sites require secure transactions, order processing, inventory management, and user authentication. A powerful web server handles these functionalities efficiently.

2. Application Hosting

Web servers can also host applications that provide specific functionalities or services. These applications can be accessed through a web browser or other client software.

Examples of application hosting:

  • Content Management Systems (CMS): CMS platforms, like WordPress or Drupal, are hosted on web servers. They allow users to create and manage websites without much technical knowledge.
  • Web-Based Email Clients: Web servers host email clients that enable users to access their emails through a browser rather than desktop software.
  • Online File Storage: Platforms like Google Drive or Dropbox store user files on web servers, making them accessible from anywhere with an internet connection.

3. Load Balancing and Scalability

Web servers play a critical role in managing high traffic and ensuring the availability of websites. Load balancing techniques distribute incoming requests across multiple servers, preventing any single server from becoming overwhelmed.

This helps improve performance and ensures a smooth user experience.

Benefits of load balancing and scalability:

  • Faster Response Time: Distributing requests among multiple servers reduces response time and prevents delays caused by overburdened servers.
  • Improved Reliability: If one server fails, load balancers can redirect traffic to other functioning servers, minimizing downtime.
  • Scalability: Adding more web servers to the infrastructure allows handling increasing traffic loads without affecting performance.

4. Security and Authentication

Web servers also play a crucial role in securing websites and protecting sensitive user data.

This is achieved through various security measures:

  • TLS/SSL Encryption: Web servers can encrypt data transmitted between the website and the user’s browser using SSL/TLS protocols, ensuring secure communication.
  • Firewalls and Intrusion Detection Systems: Web servers implement firewalls and intrusion detection systems to identify and prevent unauthorized access attempts.
  • User Authentication: Web servers can handle user authentication, allowing access to certain parts of a website based on user credentials.


In conclusion, web servers serve a variety of purposes, ranging from hosting websites and applications to ensuring scalability, security, and performance. Understanding the role of web servers is crucial for anyone involved in the development or management of websites and online services.
