TCP port 80 is assigned to which protocol?

Explanation:
Port numbers map network services to protocols, and port 80 is the default for the Hypertext Transfer Protocol, the standard web protocol for unencrypted pages. HTTPS uses port 443, SSH uses 22, and FTP typically uses 21 (with data on 20 in active mode). You can run HTTP on other ports, but the conventional assignment for port 80 is HTTP.
