Not to be mistaken for "firewall" a firewire is a new form of computer port that is faster than current ports such as serial ports. The technology of firewire was developed by both Sony and Apple, so that it will be easier and faster to connect peripheral devices such as printers, scanners, zip drives, external hard drives, digital cameras to computers. With a firewire, the above peripherals can be connected and disconnected to a computer without the need to turn the computer power off and on.
