Introduction
Web Servers are software systems that handle HTTP requests and deliver web content such as HTML pages, images, APIs, and application data to users through browsers. They act as the foundation of the internet, enabling websites and web applications to function reliably and efficiently.
Whenever a user opens a website, the web server processes the request, retrieves the required resources, and sends them back to the client. Modern web servers also support security, load balancing, caching, and application hosting.
