The IEEE-1394 High Performance Serial Bus or commonly known as 1394 or FireWire, is a high-speed serial input/output (I/O) technology for connecting peripherals to a computer. With a serial input/output technology invented by Apple Computer, FireWire can transfer data up to 400 megabits per second. FireWire connections are offered today in many notebooks, digital camcorders, and digital cameras, and some external hard drives, CD writers, and other devices.
