Question About Firewire/USB 2.0

Mon Feb 02, 2004 7:19 am

I just bought a Sony Digital Camcorder and it is supposed to connect to my PC via firewire. I currently only have USB 1.1 and was wondering do I just buy a firewire card + cable? Also, is there any difference between USB 2.0 and Firewire or are the names interchangeable for the same thing?
I used to think the brain is the most fascinating part of my body. But, hey, who is telling me that?

No, FireWire and USB are technologically very different.

While FireWire is a real device interconnection bus, USB is only a PC-centric polled peripheral connection protocol which is much less flexible and (even with USB2) much slower than FireWire.

USB 1 theoretically allows 12MBit/s
USB 2 theoretically allows 480MBit/s (in practice much slower)

FireWire also comes in two speeds, 400 or 800MBit/s, but in this case, the speed is actually attainable.

So no, you really need that extra FireWire interface for your camera, but FireWire 400 will normally suffice.
