What is the port and web page displayed when you access the website https://example.com?80, example.html443, index.html80, index.html443, example.html

When you access the website https://example.com, the port used is 443. This is because the HTTPS protocol is used, which by default uses port 443. The web page displayed depends on the server configuration, but by convention, it is often "index.html".

The numbers 80 and 443 in your question are commonly used ports for HTTP and HTTPS protocols respectively. HTTP uses port 80 and HTTPS uses port 443.

The files "example.html" and "index.html" in your question are examples of web pages that might be served by the web server. The specific page that is served when you access https://example.com would depend on the server's configuration, but by default, it is often "index.html".

So, to summarize, when you access https://example.com, you are using port 443 and likely viewing the "index.html" page, unless the server is configured differently.
