A high-speed interface, whose development was initiated by Apple. It is also known as IEEE 1394 High Speed Serial Bus. It was meant to be a replacement for the parallel SCSI bus, and also to provide connectivity to audio and video equipment. Camcorders, memory and storage devices, professional audio systems, etc. come with FireWire interfaces, as do several laptops. The data transfer rates over FireWire interfaces at 400 Mbps is comparable to that of USB 2.0, but unlike USB 2.0, the data flow rates can be sustained over a longer period of time. However, FireWire is more expensive because of licensing issues, and so is not as common as USB.
