What are the Different Types of Web Servers

The web server is the foundation of the World Wide Web.

Responsible for serving and delivering content to Internet users.

It is essential for hosting web applications and making them accessible over the internet.

If you’re looking for what a web server is and how it works?

Then you’re in the right place to know all of these answers in a descriptive guide.

Additionally, you’ll also find the ultimate list of web server software that is currently available to install on various operating systems.

So, let’s get started to learn more about web servers.

What is Web Server?

A web server is a combination of “hardware and software” installed on a physical computer that is engineered and managed by various networking systems. It uses HTTP, HTTP/2, and HTTP/3 (Hypertext Transfer Protocols) to respond to client requests made over the Internet.

They also support other protocols like SFTP (Secure File Transfer Protocol), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol) used for email, file transfer, etc.

How Does Web Server Work?

The web server primarily allocates the data space to store website files and databases accessible on the internet and defines how these data are to be exchanged with other connected devices on the World Wide Web.

The end user processes a request via a web browser, and the web server takes the request to store, process, and deliver requested information or webpages to the end user’s browsers. This communication is made between a web server and a browser using HTTP.

What are Web Servers Used For?

Web servers are primarily used to store and protect website data, control bandwidth to regulate network traffic, perform server-side web scripting, and provide virtual hosting. It uses HTTP and HTTPS protocols to process and manage requests and responses from the client system to web servers.

Web servers are mostly used for different types of web hosting services on the internet. This allows individuals and organizations to easily rent an online space to host websites or apps and make it accessible online.

What’s the Difference Between Dynamic and Static Web Servers

There are two types of web servers in terms of functionality: static web servers and dynamic web servers.

A static web server is a web server that serves only static content such as HTML, JS, CSS, etc. Whereas a dynamic server is a hybrid web server that includes a static server, an application server, and a database server that can host and serve different types of media files, including images, videos, etc.

What’s the Difference Between a Web Server and an Application Server?

A web server is a software application that serves web pages to clients, whereas an application server is a software framework that provides a runtime environment for running server-side applications.

For example, when a user requests a web page from a web browser, the web server processes the request and delivers the web page to the client’s browser for display. On the other hand, the application server handles complex business logic and performs various tasks required for building and deploying applications.

What’s the Best Operating System for Web Servers?

Generally, each type of web server software is run on one or more computers, where an operating system is required to run a computer. So, when a web server software is developed, it is important to decide which operating system it will run on!

So every web server software is compatible with one or more operating systems, including the most popular Linux servers and Distributions, Windows servers, Unix operating systems, Oracle Solaris, FreeBSD, and many more.
