How does Firewire Work?

Firewire is a protocol also known as IEEE 1394 that provides a way of transferring data quickly from between one or more devices. The difference between Firewire and USB is that where USB must route the data through a computer, Firewire will allow you to connect devices such as 2 cameras and allow them to ‘talk’ to each other directly. The ability to do this stems from the BUS capabilities built into the cables themselves.
