What processes are launched in the browser when navigating to an external web resource?

When transitioning to an external web resource, the browser performs several key processes:

1. DNS Resolution — converting the domain name to the server's IP address.
2. Establishing a connection — opening a TCP connection with the server, usually through port 80 (HTTP) or 443 (HTTPS).
3. TLS/SSL handshake (if HTTPS) — establishing a secure communication channel.
4. Sending an HTTP request — the browser sends a request to the server (GET, POST, etc.).
5. Receiving a response — the server returns HTML, CSS, JavaScript, images, and other resources.
6. Processing and rendering — the browser parses HTML, loads and applies styles, executes scripts, builds the DOM, and displays the page.
7. Performing additional requests — the browser loads all external resources specified on the page (scripts, styles, images).

This process occurs quickly and sequentially, ensuring the web page is displayed to the user.
