What happens after entering [link] into the browser's address bar?

After entering a link into the browser's address bar, several steps occur:

1. Parsing the URL: The browser analyzes the entered string to determine whether it is a URL or a search query.
2. DNS query: If it is a URL, the browser sends a request to the DNS server to obtain the IP address of the domain.
3. Establishing a connection: The browser establishes a TCP connection with the server using the obtained IP and port (usually 80 for HTTP or 443 for HTTPS).
4. TLS/SSL: If HTTPS is used, a secure connection is established.
5. HTTP request: The browser sends an HTTP (GET) request to the server.
6. Receiving the response: The server responds with HTML, CSS, JS, and other resources.
7. Rendering the page: The browser processes the received data, constructs the DOM and CSSOM, executes JS, and displays the page.

If the entered string is not a valid URL, the browser may send it as a search query to the default search engine.
