FireWire is Apple Computer’s version of a standard IEEE high-performance serial bus designed for connecting devices to a personal computer. Both Windows and Mac operating systems support FireWire.
FireWire is used to connect digital camcorders, external hard drives and other devices that can benefit from the high transfer rates supported by the connection. FireWire provides a single plug-and-play connection where up to 63 devices can be attached with data transfer of up to 400 megabits per second. FireWire can also be used to connect two computers to transfer files and to set up ad-hoc networks. In addition, FireWire hubs can be used to split connections.
