web server is a computer system or software that hosts websites

A web server is a computer system or software that hosts websites, handles client requests, and delivers content to users over the internet. It serves as the backbone of the web, allowing users to access web pages, download files, or use applications online. When users type a URL in their browser or click a link, a request is sent to the web server hosting that content, which then processes and returns the requested page or file.

  1. How Web Servers Work

Web servers function by following a client-server model:

  1. Client Request: When a user enters a URL, their browser (the client) sends an HTTP (Hypertext Transfer Protocol) request to the web server.
  2. Processing: The web server locates the requested files or data on its system and, if needed, may interact with other services (such as a database) to fulfill the request.
  3. Response Delivery: Once the content is gathered, the server sends it back to the client’s browser, which displays it as a web page or application.

Web servers handle these requests using protocols like HTTP and HTTPS (for secure connections). They manage requests quickly to provide users with a seamless browsing experience, even when handling large numbers of visitors.
