ssh

SSH stands for Secure Shell. It's like a special doorway that you can use to get into a computer or a server (a big, powerful computer). It's like knocking on the door of your friend's house and having them let you in. SSH is a secure way to get into a computer or server, because it needs a special "key" that only the person who owns the computer knows. It's like the key you use to open your house door.
