IEEE 1394b
9-pins 9 pins at one end and 4 or 6 at the other. (pg. 407)
All modern Apple Mac computers come standard with USB 2.0, Firewire (IEEE 1394a, and in some models also IEEE 1394b), and digital audio input ports.
Helo.They are 1394a &1394b. Max speed in 1394a is 400Mb/s، but max spee in 1394bis 800Mb/s.

All Macs come with AirPort WiFi built in which conforms to standard IEEE 802.11 protocols.
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.
