What is a Web Server and hosting?

A web server is a specialized computer that stores, processes, and delivers web pages to users over the internet. Web hosting, on the other hand, is the service that provides the infrastructure to make a website accessible online, allowing files to be stored and served to visitors.

Understanding the Functionality of a Web Server

How Web Servers Work

A web server operates by using HTTP (Hypertext Transfer Protocol) to communicate with web browsers. When a user types a URL into their browser, the browser sends a request to the web server hosting the website. The server processes this request and sends back the relevant web pages, images, and other files.

Key Components of a Web Server

  1. Hardware: The physical machine that runs the server software.
  2. Server Software: Software like Apache, Nginx, or Microsoft IIS that processes incoming requests.
  3. Database Management: Most dynamic websites use databases to store content, requiring database server capability (e.g., MySQL).

Types of Web Servers

  • Dedicated Servers: Exclusive use by one client, offering high performance and customization.
  • Shared Servers: Multiple clients share resources, making it cost-effective but limited in performance.
  • VPS (Virtual Private Servers): An intermediate option providing dedicated resources while sharing the physical server with others.
