Which port is used by SSH (Secure Shell)?

Explanation:
SSH uses TCP and its default port is 22. This port is the one assigned by IANA for the Secure Shell service, so clients connect to port 22 to establish a secure remote session. Other common ports are used by different services: 21 for FTP, 23 for Telnet, and 25 for SMTP. Administrators can configure SSH to listen on a different port, but the standard, widely recognized port is 22, which is why that option is the correct one.
