Summary

The web browser explains how the page ends up on the user's screen. The browser sends HTTP requests to the server, the server responds with HTML, CSS, and JavaScript, and the browser renders them all. Behind that simple loop is the role of DNS, URL, and HTTPS encryption that keeps everything going smoothly.

Key points

The browser requests a page via HTTP or HTTPS protocol
HTML is structuring, CSS is structuring the display, JavaScript is adding behavior.
DNS translates domain names into server IP addresses
HTTPS encrypts communications to keep data secure
The server responds in the form of files rendered to interactive pages
