What Is External Web Server?


Heather Bennett

An external web server is a crucial component of the World Wide Web. It plays a significant role in serving web pages to users over the internet. In simple terms, an external web server is a computer program that receives requests from clients (usually web browsers) and responds by sending back the requested web content.

How does an external web server work?
When you enter a URL in your browser’s address bar and hit enter, your browser sends a request to the external web server hosting that website. The server processes the request and sends back the corresponding HTML, CSS, JavaScript, and other files that make up the webpage.

The components of an external web server:

  • Hardware: The physical machine on which the web server software runs.
  • Software: The program responsible for handling client requests and serving web content.
  • Operating System: The underlying software that manages hardware resources and enables communication between software applications and hardware components.
  • Network: The infrastructure that connects the external web server to the internet, allowing it to communicate with clients.

Types of external web servers:
There are several popular types of external web servers available today. Some of them include:

A) Apache HTTP Server:

The Apache HTTP Server is one of the most widely used open-source web servers.

It’s known for its stability, security, and flexibility. Apache supports various operating systems and can handle high traffic loads efficiently.

B) Nginx:

Nginx is another popular open-source web server known for its speed and scalability. It’s often used as a reverse proxy or load balancer to distribute incoming requests across multiple servers.

C) Microsoft Internet Information Services (IIS):

IIS is a web server developed by Microsoft and primarily designed for use on Windows servers. It integrates well with other Microsoft technologies and offers features like Active Directory authentication and ASP.NET support.

D) LiteSpeed Web Server:

LiteSpeed is a high-performance web server that aims to deliver exceptional speed while consuming fewer resources. It’s compatible with Apache configurations, making it easy to switch from Apache to LiteSpeed without major modifications.

In summary, an external web server is a crucial component of the internet infrastructure. It receives requests from clients, processes them, and sends back the requested web content.

Understanding the various types of web servers available can help you choose the most suitable option for your website or application. Whether it’s Apache, Nginx, IIS, or LiteSpeed, each server has its unique features and advantages. So next time you browse the web, remember that behind every webpage you visit lies an external web server working tirelessly to deliver the content you see on your screen.
