IEEE 1394 is a standard type of connection for many different kinds of devices. Generally, it refers to the types of cables, ports and connectors used to connect these many types of external devices to computers. IEEE 1394 is commonly called FireWire, the Apple Inc. brand name for the standard.
The IEEE 1394 standard is a popular one for hardware requiring high data transfer rates. FireWire ports and cables are used to connect devices such as digital video cameras, some printers, scanners, external hard drives and more to a computer.
Thunderbolt is a potential replacement for FireWire.
