Explanation

SSH (Secure Shell) is the industry-standard protocol for secure, encrypted remote command-line access to UNIX and Linux systems, operating on TCP port 22. It replaced the older, insecure Telnet and RSH (Remote Shell) protocols, which transmit data including credentials in plaintext. SSL is a transport-layer encryption protocol used primarily to secure web traffic (HTTPS), not for interactive remote shell sessions. RDP (Remote Desktop Protocol) is Microsoft's graphical remote access protocol, primarily used for Windows systems. RSH is the legacy predecessor to SSH and is considered insecure and obsolete.
