SSH
Domain: Computer Systems
🎯 Motivation
Secure Shell - a protocol for securely accessing a remote computer’s command line.
📋 Concrete Example
SSH: ‘ssh user@server.com’ from your laptop. You get the server’s terminal as if you were sitting in front of it. Encrypted, secure. Used for managing remote servers.
🔗 Analogy
SSH is like a remote control for a computer - you sit at home and control a server in a data center. You see its terminal, type commands, run programs. All encrypted so no one can eavesdrop.
