Hi, my name is Dave Andrews. Today, I'm going to talk to you about firewire ports. Now, firewire is basically a connection type. You may have already heard of USB, but firewire is a connection type that's, you know, it's very common in Apple, and it's made its way also into the PC world. There's two different types of firewire. There's firewire 400 and there's firewire 800, and they differ both in design and speed. I'm going to show you a device here that has two firewire ports, and one of these is a 400 which is this port right here, and the other port is an 800 which is this port, and it also supports USB this particular device. Now, you have to have a firewire cable, and the 400 and the 800 cables actually are different. This one here is an 800 cable, and as you can see it has that sort of block interface just like the 800 port has. So you basically, to plug it in you just line these two up, plug in your 800 port right there. Now, the 400 port is a little bit different in that it has more of a sort of a straight and flat design, as opposed to the blocky design, and it will only plug into the 400 port right there, as you can see. So, it's important to know that you have to have the correct cables, you have to have the correct port, and your computer must also support the correct type of port in order to use firewire. My name's Dave Andrews, and I've just told you a little bit about firewire ports.
