IEEE1394 is an external bus standard or peripheral interface that supports data transfers of 400mbps. Apple originally developed the technology, but uses the trademarked name FireWire.
FireWire connects digital cameras, scanners, hard drives, CD-Rs and other high-speed peripherals to Macs.
The 1394 Developer's Conference will host a range of presentations. One will focus on the new IEEE1394b specification, which has bandwidths of 800Mbps and scalability of 3.2GBps.
