Which port is used for HTTPS?

• A. 80
• B. 53
• C. 25
• D. 443

Answer: (D)

HTTPS uses TLS/SSL to encrypt web traffic, so it runs on a dedicated port by default. When your browser connects to a secure site, the TLS handshake happens on port 443, establishing the encrypted channel before HTTP data is exchanged. This is different from standard HTTP, which uses port 80, and other well-known services sit on their own ports (like DNS on 53 or SMTP on 25). You can run HTTPS on non-standard ports, but 443 is the default, widely used port for secure web traffic.
