How Websites Work
Welcome to the next lesson! Today, we’ll learn how websites work behind the scenes. Understanding this will help you see the big picture of web development.
2
What is a Website?
A website is a collection of web pages hosted on a server. These pages are written using HTML, CSS, and JavaScript.
When you visit a website, your browser loads its files and displays them on your screen. Let’s explore how this process works!
3
The Role of Web Servers
A web server stores the files that make up a website, such as HTML, CSS, JavaScript, and images. It sends these files to your browser when you request a website.
Example:
- When you type
www.example.cominto your browser, it sends a request to the web server hosting that website. - The server responds by sending back the website files.
Tip: Servers can be physical machines or cloud-based systems.

How Browsers Display Websites
Your browser, like Chrome or Firefox, is responsible for interpreting the website files and displaying them on your screen. Here’s how it works:
- The browser reads the HTML file to structure the content.
- It applies CSS to style the content.
- It runs JavaScript to add interactivity.
All these steps happen in seconds!
5
How the Internet Works
The internet is a network of computers connected globally. Websites are accessed using the HTTP or HTTPS protocols, which allow your browser and the server to communicate.
Key Terms:
- HTTP: Stands for HyperText Transfer Protocol, used for transferring website data.
- HTTPS: A secure version of HTTP that encrypts data.
- URL: The address of a website, like
https://www.example.com.
6
Domains and Hosting
Two essential components of a website are:
- Domain Name: The human-readable address of a website, such as
example.com. - Web Hosting: The service that stores your website files on a server and makes them accessible online.
Tip: Think of a domain as the address and hosting as the house.
7
Client-Server Communication
When you visit a website, your browser (the client) sends a request to the server. The server processes the request and sends back the necessary files.
Example:
- You type
example.comin your browser. - The browser sends a request to the server.
- The server responds with the website’s HTML, CSS, and JavaScript files.
- The browser displays the website on your screen.

Website Performance
The speed and responsiveness of a website depend on several factors:
- How well the website is coded.
- The speed of the web server.
- The user’s internet connection.
Tip: Optimized images and clean code can improve website performance.
