A program which uses HTTP for working documents that produce webpages for users in reaction to their requests which are sent from the HTTP customers of their pc is referred to as a server.
If any server provides an XML file to a different device, it may be an internet server. That is to say, a web server is an Internet server which responds to HTTP requests for providing services and content.
So, you will insert this URL into your browser and press enter. That’s it!
The web server on which your website is based in the world doesn’t matter at all as the page you have browsed immediately appears on your computer screen.

A web server is never disconnected from the internet. Each of the web servers has a unique address that comprises of a series of four numbers between 0 and 255. These numbers are separated with a period (.) .
With the web server, the hosting providers can manage multiple domains (users) on a single server.
Linux and Windows Server Hosting services provider rents the space on a server or cluster of servers for people to create their online presence with a website.
Types of Web Servers
There are mainly four types of web servers — Apache, IIS, Nginx and LiteSpeed.
Apache Web Server
Apache web server is one of the most popular web servers developed by the Apache Software Foundation. Open source software, Apache supports almost all operating systems such as Linux, Windows, Unix FreeBSD, Mac OS X and more. Approximately, 60% of the machines run on Apache Web Server.
You can easily customize an apache web server due to its modular structure. Since it’s an open source, your own modules can be added to the server when you want to make modifications to suit your requirements.
It is highly stable as compared to other web servers and the administrative issues on it can be resolved easily. It is possible to install Apache on multiple platforms successfully.
The Apache’s latest versions offer you the flexibility to handle more requests when compared to its earlier versions.
IIS Web Server
A Microsoft product, IIS is a server that offers all the features such as Apache. Since it’s not an open source, adding personal modules as well as modifying becomes a bit difficult.
It supports all the platforms that run Windows operating system. Additionally, you also get good customer support, if there is any issue.
Nginx Web Server
Nginx is the next open source web server after Apache. It comprises of IMAP/POP3 proxy server. The significant features offered by Nginx are high performance, stability, simple configuration and low resource usage.
No threads are used to handle the requests by Nginx, instead a highly scalable event-driven architecture that uses small and predictable amount of memory under load is utilized. It has become popular recently and hosts about 7.5% of all the domains globally. Many web hosting companies have started using this server.
LightSpeed Web Server
A high-performance Apache drop-in replacement, LiteSpeed (LSWS) is the 4th popular web server on the internet and is a commercial web server.
When you upgrade your web server to LiteSpeed, you will experience improved performance that too with low operating cost.
This server is compatible with the most common Apache features such as .htaccess, mod_rewrite and mod_security.
It has the ability to load Apache configuration files directly and work as a drop in replacement Apache with almost all the hosting control panels. It can replace the Apache within 15 minutes without any downtime.
LSWS replaces all the Apache functions which other front-end proxy solutions can’t do to simplify the use and make the transition from Apache smooth and easy.
An open source Java servlet container, Apache Tomcat functions as a web server. A Java program that expands the capabilities of a server is called as a Java servlet. Servlets can respond to any types of requests but they most commonly implement applications hosted on web servers. These web servlets are Java equivalent to other dynamic web content technologies such as PHP and ASP.NET. Sun Microsystems donated Tomcat’s code base to the Apache Software Foundation in 1999 which became a top-level Apache project in 2005. Currently, it powers just under 1% of all websites.
Released under the Apache License version 2, Apache Tomcat is typically used to run Java applications. But, it can be extended with Coyote, so that it can also perform the role of a normal web server that serves local files as HTTP documents.
Often, Apache Tomcat is listed among other open source Java application servers. Some examples are Wildfly, JBoss, and Glassfish.
Node.js is released under a mix of licenses.
Pronounced as”softly”, Lighttpd was initially release in March 2003. It currently runs approximately 0.1% of all websites and is distributed under a BSD license.
Lighttpd stands unique due to its small CPU load, low memory footprint, and speed optimizations. An event-driven architecture is used by it and is optimized for a large number of parallel connections, and supports FastCGI, Auth, Output-compression, SCGI, URL-rewriting and many more features. It is a popularly used web server for the web frameworks such as Catalyst and Ruby on Rails.
There are also some other types of servers as below:
Mail Server: In a mail server, you get a centrally-located pool of disk space to store and share different documents in the form of emails for network users. All the data is stored in a single location and so, administrators need to backup files only from one computer.
Application Server: It acts as a set of components which can be accessed by the software developer via an API defined by the platform itself. These components are usually performed in the environment similar to its web server(s) for the web applications. Their main job is to support the construction of dynamic pages.
File Transfer Protocol (FTP) Server: A separate control and data connections are used by the FTP between the client and the server. It is possible for the FTP users to authorize themselves in the form of a username and password.
However, they can connect using anonymous names, if the server isn’t configured to allow them. For transmission security, the username and password need to be encrypted using the FTP and SSL.
Database Server: A computer program that offers database services to other computer programs or computers with the use of client-server functionality is called as a database server. There are some DBMSs (example: MySQL) depend on the client-server model for database access. This type of server is accessible either via a”front end” that runs on the user’s computer where the request is made or the”back end” in which it’s served like data storage and analysis.
Domain Name System (DNS) Server: A computer server which hosts a community support for supplying responses to questions is known as a server. It maps an addressing element or numerical identification. This is carried out by the host to provide response to some community support protocol request.
These DNS servers chiefly interpret the human- memorable domain names and host names to the corresponding numerical Internet protocol (IP) addresses. DNS also will help recognize a namespace of the Internet, used to identify and find computer resources and systems on the Internet.
The web hosting firms mainly choose the web servers depending on the need of customers, the amount of customers on a single host, the applications/software customers use and the total amount of visitors a web server may handle created by the customers. Therefore, while picking a web server to begin with believe on these facets and then pick one.Read More
