What Is Web Development?
Web development is the process of creating and maintaining websites and web applications that operate through the internet or private networks.
It involves both technical programming and practical problem-solving. Web developers write code that controls how websites look, function, communicate with servers, store information, and respond to users.
Web development can include:
- Website development
- Web application development
- Frontend development
- Backend development
- Full-stack development
- Database development
- API development
- E-commerce development
- Cloud-based applications

A modern website may use many technologies working together. For example, a user may interact with a frontend interface while a backend server processes requests and a database stores information.
How Does Web Development Work?
Web development generally involves several connected components.
When a user opens a website, the browser sends a request to a web server. The server processes the request and returns the necessary files or information.
The browser then displays the website to the user.
A simplified web development process can look like this:
User → Browser → Server → Application → Database → Server → Browser
Different technologies are responsible for each part of this process.
Frontend technologies control what users see and interact with, while backend technologies handle server-side operations and business logic.
