What is Firewire IEEE-1394 Interface?

Question

Its to attach a camcorder to pc

Answer 1

* Like USB, IEEE-1394 is a serial bus that uses twisted-pair wiring to move data around.
* However, while USB is limited to 12 megabits per second, IEEE-1394 currently handles up to 400 megabits per second.
* USB can handle 127 devices per bus, while IEEE-1394 handles 63.
* Both USB and IEEE-1394 support the concept of a isochronous device -- a device that needs a certain amount of bandwidth for streaming data. This mode is perfect for streaming audio and video data.
* Both USB and IEEE-1394 allow you to plug and unplug devices at any time.

Most digital video cameras have an IEEE-1394 plug. When you attach a camcorder to a computer using IEEE-1394, the connection is amazing. With the right software the computer and the camera communicate, and the computer can download all of the scenes on the tape automatically and with perfect digital clarity.
