Known officially as IEEE 1394, this standard describes a peer-to-peer serial digital interface operating at 100, 200, 400, or 800 Mb/s. IEEE 1394a specifies an interface working at up to 400 Mb/s, using copper cables up to 4.5 meters long, typically, and six-pin connectors. Four-pin connectors are used with consumer devices. Extenders increase maximum distance up to about 100 meters with glass optical fiber. IEEE 1394b extends both data rate (up to 1.6Gb/s on shielded twisted pair cable) and distance, and describes architecture to support 3.2Gb/s up to 100m on optical fiber.canonglossaryus
Also known as IEEE 1394. A computer connector that permits high-speed data transfer, including downloading from a digital camera. Data transfer is faster than USB. Accessories with FireWire capability can be plugged in and removed from the computer without having to turn off the computer. Firewire ports are usually found on high quality video and digital cameras.
Officially known as the IEEE 1394 protocol. A high speed data transfer interface used on digital camcorders and the more expensive Digital SLR’s.
A protocol for transferring data to and from digital devices at high speed, often up to 800 megabytes per second.
