What does SSH stand for?

SSH stands for Secure Shell. It is a cryptographic network protocol that allows secure communication between clients and servers over an insecure network. SSH is widely used for secure remote administration of systems and secure file transfers. It provides a secure channel over an unsecured network by using encryption, which protects both the data being transmitted and the authentication process. This makes SSH a vital tool for managing servers and services securely in today’s networked environments. The other options do not accurately describe the SSH protocol or its functions. For example, "Secure Hyperlink Shell" and "System Shell" are not recognized terms in networking or system administration, and "Simple Shell" does not reflect the secure nature or capabilities of the SSH protocol.
