Learn Web Development – Part 1 – What is Web Development?
A beginner-friendly introduction to understanding how websites and web applications are built.
Welcome to the Learn Web Development Series. Before writing any code, it is important to understand what web development really means and how the web works behind the scenes.
In this first part, we will clearly explain what web development is, the types of web development, and how different technologies work together to build modern websites.
What is Web Development?
Web development is the process of creating, building, and maintaining websites and web applications that run on the internet.
Everything you see on websites like online stores, blogs, social media platforms, or company websites is created using web development technologies.
Web development is the complete process of building websites — from design and layout to functionality and database management.
What is a Website?
A website is a collection of web pages that are accessible through a browser using the internet.
Examples of websites include:
- Business websites
- E-commerce stores
- Blogs and news portals
- Educational platforms
- Portfolio websites
What is a Web Application?
A web application is a more advanced type of website that allows users to interact, log in, submit data, and perform actions.
Examples include:
- Online banking systems
- Social media platforms
- CRM systems
- Project management tools
Unlike static websites, web applications usually connect to databases and use backend programming languages.
Types of Web Development
Web development is mainly divided into three categories:
1. Frontend Development
Frontend development focuses on what users see and interact with in a browser.
It uses technologies like:
- HTML – Structure of the webpage
- CSS – Styling and layout
- JavaScript – Interactivity
If you are new, you can start with our Learn HTML Series.
2. Backend Development
Backend development focuses on server-side logic, databases, authentication, and business logic.
Common backend technologies include:
- PHP
- Node.js
- Python
- ASP.NET
3. Full Stack Development
A full stack developer works on both frontend and backend technologies.
They can build a complete web application from start to finish.
How Web Development Works (Simple Overview)
Here is a simplified flow of how web development works:
- User enters a website URL in browser
- Browser sends request to server
- Server processes request
- Server sends response (HTML, CSS, JS)
- Browser displays the website
This entire process happens within seconds.
