Web Development is the process of creating and maintaining websites or web applications that run on the internet. It involves designing the layout, coding the functionality, and ensuring a smooth user experience across different devices.

It is mainly divided into three parts:

• Frontend Development – focuses on the visual part of a website that users see and interact with (using HTML, CSS, JavaScript).

• Backend Development – handles server-side logic, databases, and application functionality.

• Full Stack Development – a combination of both frontend and backend.

Web development also includes tasks like website performance optimization, security, responsiveness, and integration with third-party services. It plays a key role in building everything from simple websites to complex platforms like e-commerce, social media, and business portals.
