What Is a Website?
A website is a collection of web pages that you visit using the internet. Every website lives on a server and can be accessed using a link (URL). Examples include Google, Instagram, Wikipedia, and YouTube.
Simple Definition:
A website is a digital place where people can read, watch, learn, shop, or communicate through the internet.
A website is a digital place where people can read, watch, learn, shop, or communicate through the internet.
Websites are built using programming languagesSpecial languages that computers understand to create websites and applications like HTML, CSS, and JavaScript. These languages work together to create the websites you see in your browser.
How Does a Website Work?
When you type a web address into your browser:
- Your browser sends a request
- A server receives it
- The server sends back website files
- Your screen displays the website
Example: When you type google.com
➡ Browser contacts Google's server ➡ Google sends data ➡ Page loads on your device

What Is a Domain & Hosting?
Domain: Website name (like google.com)
Hosting: Space where files are stored
Hosting: Space where files are stored
Domain vs Hosting Analogy
Think of a website like a house:
DOMAIN = The address of your house (e.g., 123 Main Street)
HOSTING = The actual land and building where your house sits
Just like you need both an address and a physical location for a house,
you need both a domain and hosting for a website.What Is Frontend & Backend?
Frontend
What users see (Design, Buttons)

Backend
Server, database, login systems

Frontend vs Backend: Simple Example
Frontend (Client-Side)
<!DOCTYPE html>
<html>
<head>
<title>My Website</title>
</head>
<body>
<h1>Welcome!</h1>
<p>Click the button:</p>
<button onclick="sayHello()">
Say Hello
</button>
<script>
function sayHello() {
alert("Hello, Visitor!");
}
</script>
</body>
</html>Everything the user sees and interacts with directly
Backend (Server-Side)
// Server-side code (Node.js example)
app.get('/user-data', (req, res) => {
// Connect to database
db.query('SELECT * FROM users',
(error, results) => {
if (error) throw error;
// Send data to frontend
res.json(results);
});
});
// Process login
app.post('/login', (req, res) => {
// Validate credentials
// Return success/failure
res.json({status: 'success'});
});Everything happening behind the scenes on the server
Both work together to create a complete website experience. Frontend handles what users see, backend handles data processing and storage.
