IEEE 1394

IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple, which called it FireWire. The 1394 interface is comparable to USB though USB has more market share. Apple first included FireWire in some of its 1999 Macintosh models, and most Apple Macintosh computers manufactured in the years 2000 - 2011 included FireWire ports. However, in 2011 Apple began replacing FireWire with the Thunderbolt interface and, as of 2014, FireWire has been replaced by Thunderbolt on new Macs.
