'''Firewire''' ('''IEEE 1394''': Sony's "I-Link" and Apple's "Firewire" are brand names) is a [[1995]] [[personal computer]] and [[digital video]] [[serial bus]] interface standard offering high-speed communications and isochronous real-time data services. It is defined in [[IEEE]] 1394.
The system is used commonly for connection of data storage devices and digital video cameras.
Firewire can transfer data between a computer and its peripherals at 100, 200, or 400 [[Mbps]], with a planed increase to 2 [[Gbps]]. Cable length is limited to 4.5 [[metre|metres]] but up to 16 cables can be [[daisy-chain|daisy-chained]] yielding a total length of 72 metres.
It can daisy-chain together up to 63 [[computer peripheral|peripherals]] in a tree-like structure (as opposed to [[SCSI|SCSI's]] linear structure). It allows [[peer-to-peer]] device communication, such as communication between a [[scanner]] and a [[printer]], to take place without using system memory or the [[CPU]]. It is designed to support plug-and-play and hot swapping. Its six-wire cable is not only more convenient than SCSI cables but can supply up to 60 [[watt|watts]] of power, allowing low-consumption devices to operate without a separate power cord.
Some expensive [[camcorder|camcorders]] have included this bus since [[1995]]. It is expected to be used to carry SCSI, with possible application to [[home automation]] using repeaters.
