FireWire is Apple Inc.'s proprietary name for the IEEE 1394 interface. It is also known as i.Link (Sony’s name) or IEEE 1394 (although the 1394 standard also defines a backplane interface). It is a personal computer (and digital audio/digital video) serial bus interface standard, offering high-speed communications and isochronous real-time data services. FireWire has replaced Parallel SCSI in many applications due to lower implementation costs and a simplified, more adaptable cabling system. IEEE 1394 has been adopted as the High Definition Audio-Video Network Alliance (HANA) standard connection interface for A/V component communication and control[citation needed]. FireWire is also available in wireless, fiber optic and coaxial versions using the isochronous protocols.
