When you open a website like Google or any business website, it loads within seconds. But behind this simple action, a lot of processes happen in the background.
For most people, a website is just something they open in a browser. But for business owners and learners, understanding how a website works helps in making better decisions about building and managing websites.
In this guide, we will explain everything in simple words:
- how websites started
- what happens when you open a website
- what technologies are used
- what protocols like HTTP and HTTPS mean
- how everything works together
What is a Website?
A website is a collection of web pages that are accessible through the internet.
These pages can contain:
- text
- images
- videos
- forms
- applications
Every website has a domain name (like smarttejas.com) and is stored on a server.

A Simple Example to Understand Websites
Think of a website like a shop:
- Domain name → shop address
- Hosting server → shop building
- Website pages → products inside the shop
When a user visits your website, they are simply entering your “digital shop”.
A Brief History of Websites
Understanding the history makes it easier to understand how websites evolved.
The Beginning of the Web
The World Wide Web was invented by Tim Berners-Lee in 1989.
His goal was simple:
👉 To share information easily across computers.
He introduced:
- HTML (for creating pages)
- HTTP (for communication)
- Web browsers
First Website
The first website was created in 1991.
It was very simple:
- only text
- no design
- no images
Home of First Website: http://info.cern.ch
Evolution of Websites
1. Static Websites (Early Days)
- simple pages
- no interaction
2. Dynamic Websites
- database-driven
- user interaction
3. Modern Web Applications
- login systems
- dashboards
- e-commerce
- SaaS platforms
Today, websites are powerful tools for business operations.
What Happens When You Open a Website?
Let’s understand step-by-step what happens when you type a website URL.
Step 1: You Enter a URL
Example:
👉 www.smarttejas.com
Step 2: Domain Name is Converted to IP Address
Computers don’t understand names—they understand numbers.
So your domain is converted into an IP address using DNS.

Step 3: Request Sent to Server
Your browser sends a request to the server where the website is hosted.
Step 4: Server Responds
The server sends back:
- HTML
- CSS
- JavaScript
- images
Step 5: Browser Displays the Website
Your browser (like Google Chrome) processes the files and shows the website.
What is a Web Server?
A web server is a computer that stores website files and sends them to users when requested.
It runs 24/7 so your website is always available.
Popular web servers include:
- Apache
- Nginx
What is DNS (Domain Name System)?
DNS works like a phonebook.
It converts:
👉 domain name → IP address
Without DNS, we would have to remember numbers instead of domain names.
Understanding Website Protocols
Protocols are rules that define how data is transferred.
What is HTTP?
HTTP stands for HyperText Transfer Protocol.
It is used to transfer data between:
- browser
- server
What is HTTPS?
HTTPS is the secure version of HTTP.
It uses encryption to protect data.
This is where SSL comes in.
What is SSL?
SSL encrypts data so that it cannot be read by hackers.
It ensures:
- secure login
- safe transactions
- data protection

Technologies Behind a Website
Websites are built using different technologies.
1. Frontend (User Interface)
Frontend is what users see.
Technologies:
- HTML → structure
- CSS → design
- JavaScript → interaction
2. Backend (Server Side)
Backend handles logic and data.
Technologies:
- PHP
- Python
- Node.js
3. Database
Stores data such as:
- users
- orders
- reports
Popular databases:
- MySQL
- PostgreSQL
Example: How Everything Works Together
When you login to a website:
- You enter username/password
- Data goes to server
- Server checks database
- Response is sent back
- You are logged in
What is Hosting?
Hosting is where your website files are stored.
Companies like Hostinger provide servers to host websites.
What is Browser?
A browser is software used to open websites.
Examples:
- Google Chrome
- Firefox
- Edge
Types of Websites Today
Static Websites
- fixed content
- simple
Dynamic Websites
- interactive
- database-driven
Web Applications
- advanced systems
- dashboards
- SaaS platforms
