How Websites Work: A Beginner's Guide to Browsers, Servers, and Databases

A website is essentially a collection of files stored on a remote computer, delivered to a user's browser over the internet using HTTP, a standardized communication protocol. The browser, acting as the client, sends requests to a server, which processes them and returns the appropriate files or data. Web development is divided into frontend — the visual layer built with HTML, CSS, and JavaScript — and backend, which handles server-side logic using technologies like Node.js or Python. Databases such as MySQL or MongoDB store all persistent data, including user credentials and content, which the backend retrieves as needed. Together, these three layers — frontend, backend, and database — form the complete architecture of any modern website.
