What Does a Web Server Do?

Welcome Dev, in this article we will discuss the fundamental role of a web server. If you are wondering what a web server does and why it is important in today’s digital age, then you are in the right place. Here we will delve into the core functionalities of a web server, how it works, and why it’s essential for hosting a website.

What is a Web Server?

Before we explain what a web server does, it is important to first understand what a web server actually is. In simple terms, a web server is a computer program that delivers web pages to clients or users over the internet. It is a software application that provides web-based services to users using Hypertext Transfer Protocol (HTTP).

A web server is a vital component of the internet infrastructure because it facilitates the process of communicating data between the server and client devices such as laptops, smartphones or tablets. It stores, processes, and delivers web files such as HTML pages, images, videos, and other multimedia content that make up a website.

How Does a Web Server Work?

A web server works by following a set of protocols and standards that enable it to communicate with web browsers and other devices connected to the internet. When you type in a website address in your browser, it sends a request to the web server that hosts the website. The web server then responds to the browser’s request by sending the appropriate files, such as the HTML file, that make up the webpage.

The web server uses the HTTP protocol to transfer data between the server and the client device. This protocol defines how data is transmitted between the two devices and ensures that the data is not corrupted during transmission.

Types of Web Servers

There are several types of web servers available in the market, each specially designed to cater to specific website hosting requirements. Some of the most popular web servers include:

What Does a Web Server Do?

1. Host Websites

A web server is primarily responsible for hosting websites. It stores and serves website files including HTML documents, images, videos, and other multimedia files. It enables users to access the website over the internet via their web browsers.

2. Process User Requests

When a user requests a web page, the web server processes the request and sends the requested files to the user’s web browser. The server may also process other requests such as form submissions or database queries.

3. Manage User Sessions

A web server can manage user sessions by tracking user activity and maintaining user information such as login credentials and preferences.

4. Load Balancing

Load balancing is a feature that enables a web server to distribute incoming traffic among multiple servers to prevent overloading and ensure efficient use of resources. This feature ensures that the website stays online and responsive, even under heavy traffic loads.

5. Security and Authentication

A web server can provide security features such as encryption and authentication to protect user privacy and prevent unauthorized access to website files or user data.
