Which port number is associated with HTTPS?

• A. 80
• B. 443
• C. 22
• D. 25

Answer: (B)

Secure web traffic uses HTTPS, which is HTTP over TLS/SSL. The standard port for HTTPS is 443, chosen to be distinct from the plain HTTP port 80. When you visit a site with https in the URL, the browser connects to the server on port 443 by default. Other common ports like 80 for HTTP, 22 for SSH, and 25 for SMTP are tied to their respective services, but the default for secure web traffic is 443. Administrators can configure different ports, but 443 remains the default for HTTPS.
