IEEE 1394 is the full name, and it is just the technical name for FireWire.
The port will tell you what the speed is, if it is a 9 Pin port, then it is FireWire 800, if it only has 6 Pins or 4 Pins then it is FireWire 400.
The 4 Pin port can not be used with any device that requires bus power, meaning most card readers.
For some more info, and pictures of the different ports, go here.
