i.LINK, also known as IEEE 1394 or FireWire, is an extremely fast (up to 400 megabits per second), two-way digital connection used between computers and peripherals like digital camcorders. It is used in digital camcorders because it is one of the few connections capable of quickly transferring full-motion video. Most consumer video equipment uses 4-pin i.LINK ports and connectors, but some peripherals employ a 6-pin i.LINK configuration.
