Before Windows and Mac came on the scene with their flashy Graphical User Interfaces we had workable solutions. I still have a computer that I ran Direct Access where I found out about creating links. So I can assert without reservation that everything that went into a GUI has it's roots in Microsoft or Apple. Take for instance - Fully Qualified Domain Names:
1) Open your Command Line utility - RUN.
2) Type "ipconfig" click the OK button.
Use this IP Address to view the Fully Qualified Domain Name (FQDN) of the Server.
3) Type "ping -a IP" where "IP" is the IP address for the computer. Press ENTER. The "-a" switch returns the domain name of your server.
All in common DOS commands.
