What protocol does SQL Server use on a network? TCP or HTTP or FTP?

  • I have been asked this and should know the answer, but I am cut to the quick. I have 2 servers, one accessing another across a network. Would that be TCP? OR HTTP? Or what protocol? I don't know too much about network terminology.

  • TCP

    HTTP is a hypertext transfer protocol.

    FTP is a file transfer protocol.

  • Thank you for your response. Now I am really confused - The original question that I was asked said something like "Do we get the data via FTP (like some feeds) or HTTP (obviously for web sites, etc), but then, I got to thinking, when I set up a linked server, what protocol does that use, or how an application would communicate with the server or a web front end (I suppose that would be http), but I think they want to know how the "client" instance will communicate with the main server.
