Computer Lesson #3

ok, this will be the first "short computer lesson" that is actually short...

USB vs. Firewire
I won't get into all of the differences in the 2, but rather just talk about the transfer speeds, about which many people are misinformed...

-USB 1.1 can transfer data at 12Mbps (1,024 bits per second)
-Firewire can transfer data at 400Mbps
-USB 2.0 can transfer data at 480Mbps
-Firewire 800 can transfer data at 800Mbps

I suppose it is because Firewire came out before USB 2.0 and because Intel delayed integrating USB 2.0 support in their chipsets that Firewire became known as "much faster than USB".

There are very few Firewire 800 devices available as of now, and the only popular machine that comes with support for such devices is the 17'' Apple PowerBook.

Also, it is worth noting that USB 1.1 devices will work with a USB 2.0 machine, it will just run at USB 1.1 speed. USB 2.0 devices will not work with a USB 1.1 machine.

This lesson deemed extremely insightful and of much help Josh. And seriously how hot does Firewire really get?
