The IEEE 1394 bus complements the Universal Serial Bus (USB) and is particularly optimized for connecting digital media devices and high-speed storage devices to a PC.
IEEE 1394 is a peer-to-peer bus. IEEE 1394 devices have more built-in intelligence than USB devices, and they run independently of the processor, resulting in better performance.
The 100-Mbps, 200-Mbps, and 400-Mbps transfer rates currently specified in the IEEE 1394a standard and the proposed enhancements in IEEE 1394b are well suited to meeting the throughput requirements of multiple streaming input/output devices connected to a single PC.
