What does SSH stand for?

SSH stands for Secure Shell. It is a cryptographic network protocol used to securely connect to a remote computer or server over an insecure network. The primary purpose of SSH is to allow secure communication, providing a secure channel over an unsecured network and facilitating safe data transmission and command execution.

The name "Shell" refers to the command-line interface provided by SSH, which allows users to interact with the remote system as if they were physically sitting in front of it. In addition to secure remote login, SSH also enables secure file transfers and is utilized for various administrative tasks.

The other options do not accurately describe SSH. Secure Socket Handshake refers to a different aspect of network security protocols, while Simple Secure Host and Solid State Hub are not established terms in the context of network communications or protocols. This distinction reinforces the accuracy of "Secure Shell" as the correct answer.
