Port 80 is the default port for HTTP (unencrypted web traffic), and port 443 is the default port for HTTPS (TLS-encrypted web traffic). The other options mix in unrelated ports: port 25 is SMTP (email sending), port 53 is DNS (name resolution), port 8080 is an alternate HTTP port, and port 110 is POP3 (email retrieval). None of those pairs represent standard browser-to-web-server communication.
