FireWire
Alternatively referred to as IEEE-1394, FireWire was developed by Apple in 1995 and is a bus that has a bandwidth of 400-800 Mbps, can handle up to 63 units on the same bus, and is hot swappable. Users more familiar with USB can relate FireWire to USB as it has a lot of the same similarities. Like USB, FireWire has dozens of different devices such as removable drives, cameras, etc. that can be connected to it.
