FireWire is

interface (although the 1394 standard also defines a
backplane interface). FireWire
is also known as

Panasonic’s

camcorder tapes). It is a
interface standard for high-
speed communications and
isochronous real-
time data transfer, frequently used in a
personal computer and
digital audio / digital video.
