Web Server 101: What Exactly Is a Web Server? 🤔💻
What’s a Web Server, Anyway?
Imagine a web server as the friendly librarian of the internet. When you ask for a book (a webpage), the librarian fetches it for you. But instead of books, web servers deliver HTML, images, videos, and scripts to your browser.
Technically, a web server is software that listens for HTTP/HTTPS requests from your browser and responds by sending back the requested resources. It acts as the bridge between your device and the physical server where websites live.
Hardware vs. Software
- Hardware: The physical machine (server) where websites and data are stored.
- Software: The web server application (Apache, Nginx, etc.) that handles requests and responses.
Why Web Servers Matter
Without web servers, your favorite sites like Netflix, TikTok, or Adobe wouldn’t load. They ensure fast, secure, and reliable communication between you and the internet.
