Thread: What is FireWire (IEEE 1394)

FireWire is used for high-speed data transfers. It is found in two variants-FireWire 400 and FireWire 800. The data transfer speeds attained by FireWire 400 and FireWire 800 connections are 400 Mb/s and 3200 Mb/s respectively. Both are usually used for importing video from camcorders or hard drives, but are losing out to high-speed USB 2.0.
