  1394 Trade Association: Technology
The 1394 digital link standard was conceived in 1986 by technologists at Apple Computer, who chose the trademark 'FireWire', in reference to its speeds of operation.
It was adopted in 1995 as the IEEE 1394 standard.
The low overhead, high data rates of 1394, the ability to mix real-time and asynchronous data on a single connection, and the ability to mix low speed and high speed devices on the same network provides a truly universal connection for almost any consumer, computer, or peripheral application.

 Firewirestuff: What is FireWire IEEE 1394?
The 1394 digital link standard was conceived in 1986 by technologists at Apple Computer, who chose the trademark 'FireWire', in reference to its speeds of operation and the thermal "noise" created in the connections when the highest speeds were implimented.
The low overhead, high data rates of 1394, the ability to mix real-time synchronous and asynchronous data on a single line and the ability to mix low speed and high speed devices on the same single network connection, provides a truly universal connection for almost any consumer or commercial peripheral application.
1394 however would have to be the storage media interface of choice over all others because of "real time", synchronous / asynchronous peer to peer data transfer and future potential over wireless and fiber.

Some of these 1394 connections can become dedicated on the fly, so that devices which are time sensitive can maintain a connection at a constant data transfer rate (this would keep your streaming video from being jumpy and audio from becoming distorted).
1394 eliminates this by reducing the highway to one lane but allowing the cars to go as fast as possible and packing them bumper to bumper (as shown on the next page).
Each time a 1394 device is added to or removed from the serial bus, the 1394 bus reconfigures itself.

 KODAK: Technical Overview: IEEE 1394
IEEE 1394 is a high-speed serial bus particularly adept at carrying digital video such as the images captured in a digital camera.
However, unlike USB, IEEE 1394 is a true peer-to-peer interface—a PC is not required to connect between various peripherals.
IEEE 1394 is based on a shared-memory model, which allows devices to directly access locations in memory as needed instead of having to wait for information to flow by in a stream.

 1394 Node
A 1394 node is an addressable entity on the 1394 bus.
