What
is a Web Server?
A web server is a software application that serves and
delivers web content to client devices over the internet. It handles requests
from web browsers or other client applications and responds by sending the
requested files, such as HTML documents, images, videos, or any other type of
content.
When a user enters a website's URL in their web browser,
the browser sends a request to the web server associated with that website. The
web server processes the request, retrieves the relevant files or data, and sends
them back to the client's browser, which then renders and displays the content
to the user.
Web servers are typically equipped with high-performance
hardware and specialized software optimized for handling multiple simultaneous
requests from clients. They use protocols such as HTTP (Hypertext Transfer
Protocol) to communicate with clients and exchange information. Some commonly
used web servers include Apache HTTP Server, Nginx, Microsoft Internet
Information Services (IIS), and LiteSpeed.
In addition to serving static content, web servers can also
execute server-side scripts or applications, generating dynamic content based
on user input or database queries. These scripts can be written in languages
such as PHP, Python, Ruby, or JavaScript, and the web server includes modules
or extensions to interpret and execute these scripts.
Web servers play a crucial role in the infrastructure of
websites and web applications, ensuring that the requested content is delivered
reliably and efficiently to users around the world.
