9-pins 9 pins at one end and 4 or 6 at the other. (pg. 407)
1394 Cables have 9 pins on one end and 4 pin or 6 pin connector at the other end to connect a 1394a device to a 1394b computer port to run at a slower speed.
From Wikipedia definition of IEEE 1394 Standard - "The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer, frequently used by personal computers, as well as in digital audio, digital video, automotive, and aeronautics applications. The interface is also known by the brand names of FireWire(Apple), i.LINK (Sony), and Lynx (Texas Instruments). IEEE 1394 replaced parallel SCSI in many applications, because of lower implementation costs and a simplified, more adaptable cabling system. The 1394 standard also defines a backplane interface, though this is not as widely used."
usb 2.0 can support 127 devices
VGA, USB, Ethernet, IEEE 1394 Interfac, Paralel, PS2, Serial, DVI, SCSI, TRS, RCA. Take your pick. Remember those are categories, within each you have many more. PS: Yes they're all for external devices. Good luck, I hope you realize now is the time to give up on computers. Its just not for you
The IEEE 1394 interface was created by Apple and is marketed as FireWire on their computers. In theory you run a FireWire cable from the 1394 connection on your TV to a FireWire socket on your Mac and use some recording software to capture the HDTV signal. In the real world things are never that simple. The IEEE 1394 interface on the TV is usually there to connect cable TV boxes rather than streaming HD content. There are ways to make this work but there are also many variables (make of TV etc.) that will prevent it from working. (See links below for a fairly old discussion about the topic). A modern Intel Mac is quite capable of recording HDTV through a USB device, connected directly to the Mac, such as those made by Elgato using their EyeTV software.

The system can support 4 devices.
Linux distributions can support hundreds of thousands of devices and programs, far too many to list.
