IEEE1394 Serial bus : Firewire in the Home

The IEEE1394 serial bus is a low cost and high performance bus that interconnects consumer electronics audio video devices and PCs. The 1394 bus enables simple interconnections between devices with a single cable wire. The devices can be plugged in and out of the 1394 network while they are in powered on stage, i.e., hot pluggable. The devices get automatically detected and configured without any necessity for manual configuration. The devices can talk to each other, i.e., peer-to-peer communication, without any intervention or support of Personal Computers. The 1394a standard bus supports 100,200,400 mbps speeds and 4.5 meter cabling. Whereas the latest 1394b standard supports speeds 100,200,400,800 up to 3.2Gbs and Plastic optical cabling (POF) up to 100 meters.
