    I'd suggest the TCP protocol, which Beej describes in his tutorial, for simple data transfer between two or more computers on a LAN; UDP (which Beej also describes) for data transfer over the internet, or for high-speed data transfer over a LAN.

    You could either use the BSD socket routines, (i.e. Winsock on Windows) or the SDL_Net library. I'd recommend the SDL_Net library if you're doing some kind of game programming, mainly because it requires the SDL to begin. Note that you _can_ use SDL_Net without using the SDL graphics library.

    UDP for data transfer over the internet
    ???

    You use UDP when you mostly have one-way communication and when you don't care if a package doesn't arrive, or after one that was sent later. You use TCP when you need a reliable connection.

    I'd recommend the SDL_Net library if you're doing some kind of game programming, mainly because it requires the SDL to begin.
    Games don't require SDL. You can use it, but you don't need it.

    Security. Once you do socket programming, you're exposing your programs to the evil that is out there. Learn what causes security holes and learn how to avoid them.
