A high-speed data exchange protocol, it provides a single plug-and-socket connection on which up to 63 devices can be hung. Additionally, the technology allows for hot-swapping devices, while data transfer allows for speeds of up to 400 Megabits per second. Common on personal computers these days, IEEE 1394 is implemented by Apple as FireWire, and by Sony as iLINK.
