📘 Lesson Content

🔹 What is Web Development?

• Web development is the process of building and maintaining websites.

• It includes designing, coding, and managing websites and web applications.

🔹 Types of Web Development

• Front-End Development

  • Focuses on the user interface — what you see on the screen.

  • Uses languages like HTML, CSS, and JavaScript.

• Back-End Development

  • Focuses on the server-side — databases, server logic, user authentication.

  • Uses languages like PHP, Python, or Node.js.

• Full-Stack Development

  • Combines both front-end and back-end skills.

  • A full-stack developer can build and manage an entire website or web app.

🔹 How Websites Work (Client-Server Model)

• The client (e.g., your browser) sends a request to the server.

• The server processes the request and sends back the website content.

• This communication uses the Internet and follows protocols like HTTP.

🔹 Basic Tools for Web Development

• Code Editor (e.g., VS Code, Sublime Text) — for writing code.

• Web Browser (e.g., Chrome, Firefox) — for testing websites.

• Version Control (e.g., Git) — for tracking code changes.
