    Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

    Fewer Letters More Letters

    IP Internet Protocol
    SSH Secure Shell for remote terminal access
    SSL Secure Sockets Layer, for transparent encryption
    TCP Transmission Control Protocol, most often over IP
    VNC Virtual Network Computing for remote desktop access
    VPN Virtual Private Network
    VPS Virtual Private Server (opposed to shared hosting)
