FireWire (technically known as an IEEE 1394 interface) is an interface developed by Apple that allows you to plug peripherals such as video cameras into your computer. Most Macs come with a FireWire interface, some Windows PCs have fireWire built in or they can have it added by adding a FireWire card. Some manufacturers adopt their own name for the IEEE 1394 interface; Sony, for example, call it an iLink. If you have a camera, or some other peripheral, with a FireWire interface it will have come with a FireWire cable which you plug into your computer to allow the two to connect so you can transfer your video/images from the camera to the computer.

Unless external heat is added lead remains at ambient temperature.
External data is something that is added to a device to increase its storage capacity. An example of this would be an SD card that you put in a cell phone.
