Why Do We Require Web Server?

When it comes to accessing information on the internet, we rely heavily on web servers. In this article, we will explore the importance of web servers and why they are essential for the functioning of websites.

The Basics

What is a Web Server?

A web server is a computer program that delivers web content to users upon request. It acts as a mediator between the user’s browser and the website’s files, ensuring smooth communication and efficient delivery of data.

Key Functions

Serving Web Pages

A primary function of a web server is to store and serve web pages. When a user enters a URL in their browser, the browser sends a request to the web server, which then fetches the requested page and sends it back to the browser for display.

Handling Requests

A web server is responsible for handling multiple requests simultaneously. It manages incoming requests from users, allocates resources, processes them in an orderly manner, and responds with the requested data.

Types of Web Servers

Apache HTTP Server:

  • The Apache HTTP Server is one of the most popular open-source web servers widely used today.
  • It offers robustness, flexibility, and compatibility across various operating systems.
  • Apache supports multiple programming languages like PHP, Python, and Perl.


  • Nginx is known for its high performance and scalability.
  • It efficiently handles concurrent connections without consuming excessive system resources.
  • Nginx is often used for serving static content or as a reverse proxy for load balancing.

Microsoft Internet Information Services (IIS):

  • IIS is a web server developed by Microsoft.
  • It provides seamless integration with other Microsoft technologies like ASP.NET and Windows Server.
  • IIS offers advanced security features and reliable performance for hosting websites on Windows servers.

Benefits of Web Servers

Improved Website Performance:

A well-configured web server can enhance website performance by efficiently handling requests, optimizing resource allocation, and caching frequently accessed content. This results in faster response times and improved user experience.


Web servers allow websites to handle a large number of concurrent users and traffic. They can be configured to automatically scale resources based on demand, ensuring that the website remains accessible even during peak periods.


Web servers offer various security mechanisms to protect websites from unauthorized access, such as SSL/TLS encryption, firewalls, and access control configurations. These measures help safeguard sensitive user data and prevent malicious attacks.

In Conclusion

A web server plays a crucial role in delivering web content to users effectively. It serves as the backbone of websites, handling requests, optimizing performance, and ensuring secure communication. Understanding the importance of web servers is essential for anyone involved in website development or management.
